This is a new mesh, and means that it's a brand new self contained object that usually does not require a specific Expansion pack (although this is possible depending on the type). It may have Recolours hosted on MTS - check below the description for more information.
Title: Universal Rooftop Antenna in Three Sizes, with Slots

Updated January 11, 2008: SDrooftopantenna_master.package, SDrooftopantenna_medium.package and SDrooftopantenna_small.package, the three antenna mesh files, now have four slots to contain accessories and - possibly - FreeTime wild birds. The new index picture shows an evening lightning strike on a large antenna equipped with a light and lightning rod. If you have been using these antennas in the game previously you will need to sell and replace them for these new features to work. Please see Post #26 for details.

Updated January 6, 2008: The files for the three sizes of antenna - SDrooftopantenna_master.package, SDrooftopantenna_medium.package and SDrooftopantenna_small.package - have now been updated to work with all versions of the game. For Base Game through to Pets you will need to use the procedure described in Post #23 for placement on a sloping roof.

For users of Seasons or later expansion packs, you will be able to place the antenna directly on the roof, as before. The antennas have also been made attractive to lightning, now as attractive as trees. However, just as with the Seasons lightning rod, lightning will not strike these antennas if they are placed on a sloping roof. It appears that the game considers that rooftop objects are actually located inside the building, and lightning is not permitted to strike objects located within a building.

Note that an antenna or lightning rod placed on the ground or on a flat roof will be attractive to lightning - the lightning rod considerably more so than either these antennas or trees. Of course, placing an antenna or lightning rod on the ground would typically look quite unrealistic.

If you had the antenna working in your Seasons game before, I am fairly certain you will need to sell it and then reinstall it on your building for the new lightning attractiveness feature to work - which will in any event only work if the antenna is on a flat roof or on the ground.


This is a set of three sizes of rooftop radio and television antennas, based on the Seasons lightning conductor. Each antenna is available in two recolourable groups. The first of these is the Yagi or antenna proper, constructed of eight horizontal elements mounted on a horizontal beam. One of these elements, the driver or dipole located in the second position from the larger or back end, is comprised of an oval loop. The second group, the Accessory subset, includes the horizontal base; vertical pole and clamp; bolts, nuts, and screws; and two flat insulating plates and a square box or "balun" located at the dipole.

Fifteen recolours of each of the two recolourable groups are included in this upload. The picture labeled "Antennas are for the birds" and an additional "AntennaDefault" picture included in the links at the bottom of this post shows the large size antenna system in its default colours.

The large, medium and small antennas cost §194, §193 and §192 respectively, and can be found in the Decorative: Miscellaneous section.

The picture above shows the antenna in its three sizes, shown in the ice, silver and white recolours. Like all these recolours, the "ice" colour on the left is filled with both a linear and radial colour gradient. It is however the only recolour in this collection that does not also contain a texture. As such, it suggests to me that it would suitable for "pure" environments such as low atmosphere space colonies. This textural purity would also make it an ideal base from which do to your own texturing and colouring.

This bright collection shows the medium antenna in pink, green and copper. Yes, that is Barbie pink, sampled from the website. Note that mixing and matching between the recolourable groups can provide some useful variations, such as pink with white, or green with copper.

These three recolours of the medium antenna are in gold, light metallic, and bronze. Note that actual antennas have been manufactured in gold, not solid gold but a gold anodized finish. Gold is both highly conductive and non-corroding.

This military/industrial collection shows the large antenna in black, grey, green camouflage, brown camouflage, and weathered. All of these colours tend to blend in with the background, so I used a plain concrete roof so that they could be seen more clearly.

Tech Notes

The large size antenna is a scale model, designed to ARRL specifications using this online calculator. This antenna is designed to operate at a frequency of 66 MHz, in the centre of the VHF-Low television band, between channels 3 and 4. The medium size antenna is scaled to operate at 118.5 MHz, the centre of the FM broadcast band. The small sized version is scaled for 193 MHz, at Channel 10 in the VHF-High television band.

These antennas use the Yagi-Uda design, very popular as a television and radio receiver antenna. But the Yagi antenna would also be appropriate for Sims 2 communications, scientific, space and military scenarios, particularly if these somewhat arbitrary scaled size designations are ignored.

The medium and small size antennas use the repository technique to reference the recolours of the large size antenna. Please recolour the SDrooftopantenna_master.package if you wish the smaller size antennas to be available in other colours. I am indebted to the Slave Object Tutorial by IgnorantBliss for making a complex procedure easy.

International Translations

Mihura has been kind enough to translate the titles and descriptions into French, German, Italian and Spanish.

Terms of Use

You may include any of these antennas in uploaded lots, whether free or for pay. You may also make and distribute your own recolours other than in lots, provided that the original meshes are not included. In either case, please provide a credit and link back to this page. It would be nice if you sent me a PM with a link to your creation, but this is not strictly necessary. Please do not upload the original meshes or recolours otherwise than in lots.

If including the medium or small size antennas in lots, please be sure to include the large size master object also, SDrooftopantenna_master.package.

I am willing to take requests for other recolours, and would also consider doing a vertically polarized Yagi or stacked array if there is sufficient interest. But note that the poly count for a stacked array would be close to double that of these horizontally polarized antennas.

SimPE, PJSE, and CEP, which together make it all possible
Milkshape 3D and Ultimate Unwrap3D Pro, for 3D modeling
Corel WEB.PhotoPaint, for texturing and colouring
Microsoft Photo Editor, for PNG file conversion and screen capture cropping
Numenor's BaseGameStarter Pro and AnyGameStarter, so handy speeding up the development process

Polygon Counts:

Each antenna size contains 4142 faces and 3346 vertices. For a model that takes up over eight tiles in its large size, this is actually quite moderate. In many typical applications, only one antenna will be used per lot.

Thank you for the encouragement, kriselt and Mihura. And thanks again Mihura for your patient work at translation!

I am looking forward to using the ice recolour at one of my space colonies. I may just spoil myself and actually play the game for a change.

As a test, I just downloaded and extracted the zip without problem. Several people have reported it working in-game.

The zip itself is fine but sometimes the download process can cause corruption when the servers are busy. The typical symptom of this is that the download completes almost instantly and you find that the archive is empty or only partially there. You will know the file has been successfully downloaded if it contains exactly 954,705 bytes.

Default Plans for a Base Game Rooftop Antenna - Now Complete!

This antenna came out of the need for a realistic finish to my current contest entry (in the moderation queue at the moment) which is an interpretation of an actual country house in France that has a rooftop antenna. Since this project - La Maison Béarnaise - requires Seasons and Nightlife, it was obvious that the lightning rod would make an ideal base object. It has the big advantage of being sensitive to a roof's location and slope - i.e. it "knows" that the roof is actually there. A bonus of using the lightning rod is that it gives Seasons players an alternative to putting a lightning rod on every house.

Yes, I am a firm believer in making basic objects such as this base game compatible. I have a good idea how it might be done and plan to have one released by month end. So I would rather you not make another one using this mesh, at least until you see how mine turns out.

If you use your own mesh well that is a different matter. On the other hand there are so many other basic objects in the Sims 2 that need either improvement or to be created from scratch that is seems a shame to devote the many hours required to duplicating this effort. So please wait and see...

BTW, there are three beam type antennas available that are base game compatible, one by frillen and two by Sim2Lew, with a vertically polarized one here. They are not however rooftop compatible, which is what I wanted.

Yes, that would be delightful! I see that FreeTime will having free-flying wild birds in it, but I suspect they will want nothing to do with this antenna!

Default Lightning Strike Anyone?
If anyone manages to capture a direct hit lightning strike on this antenna and could post a picture here that would be great fun to see! I gave it a try last night, but could not even get a lightning storm to happen. Of course, that may be something to do with testing it in a low atmosphere space colony!

#16 Old 3rd Jan 2008 at 6:43 AM Last edited by Sophie-David : 6th Jan 2008 at 11:52 PM. Reason: Updated with further information on the lightning rod
OK, I picked up Paladin's "Wrath of the Gods" weather controller, which has the ability to specifically cause lightning storms. I put one of my antennas to extensive tests and found that lightning would strike everywhere but the antenna (if only it were that way in real life it would make my job a lot easier). Therefore please do not rely on this antenna as a replacement lightning rod. I will be looking into making the antenna more attractive to lightning, but am not sure it will be possible.

Update: the lightning rod (and effective January 6 the antennas), actually attracts lightning quite nicely, *provided* it is located on a flat roof or on the ground. It appears that objects placed on the roof are considered by the game to be within the building: lightning is not permited to strike objects located within the building.

Default So What's the Deal with the Lightning Rod?
This morning I tested the original Seasons lightning rod in a hack-free AnyGameStarter environment containing just Seasons and Nightlife and got exactly the same results as I did with my antenna. The lightning would strike everywhere but the lightning rod.

Is this how it is supposed to work, the house itself is protected by the lightning rod, so instead the lightning hits all the objects - especially the trees - in your yard? This seems to be a very unrealistic way to code a lightning rod!
#20 Old 3rd Jan 2008 at 8:39 PM
I have to test this Paladin wrath Sophie-David but (in reality) if lightnings strike the lightning rod it doen't strike elsewere right ?

For the snow I place the screens. No snow on it even when all is covered but it's the same for this (famous ) lightning rod.

So a Maxis will ? :p

Thank you Mihura, what beautiful pictures! I have never seen snow so deep in my games - the house and roof are completely obscured.

Yes, antennas - and lightning rods - do ice up in this reality, but are typically too round and slippery to actually hold snow. In my job in communications technology it is the ice that can cause us a big problem, because it blocks the radio energy from reaching or being radiated by the antenna.

Yes, I would certainly expect lightning to be attracted to a lightning rod - and unfortunately also to an antenna, unless a lightning rod is protecting it. I would have thought that Maxis would have made their lightning rod the same, but from tests so far it appears that lightning avoids the lightning rod. If that is true then the antenna is working properly as a Seasons lightning rod, because lightning certainly never strikes it!

Default File Update: January 3, 2007
The object packages - SDrooftopantenna_master.package, SDrooftopantenna_medium.package and SDrooftopantenna_small.package - have been updated. Minor changes were made so that the lightning strike BHAV code specifically recognizes the antenna as a replacement lightning rod.

As I suspected, this has made absolutely no visible difference to the game: the antenna continues to be avoided by lightning strikes just the same as the Seasons lightning rod is avoided by lightning strikes. Possibly this is exactly what Maxis intended the lightning rod to do - or there is a bug in their lightning code.

So is it worth downloading this update? Personally I would not bother: the change appears to be theoretical rather than practical.

Default Jan. 6/08 Update: Universal Antenna, Lightning Attractive
The rooftop antennas are now compatible with the Base Game and all expansions. For Seasons and later expansions the antennas may be placed anywhere on a sloping roof directly, similar to the way that the lightning rod may be placed. For users of the Base Game through to Pets, the game's roof works in a different manner - this is nothing to do with the antennas themselves - and objects cannot be placed directly on the roof.

There is however a practical workaround that uses JohnBrehaut1's OMSPs, particularly the bookcase models from this set. The following procedure will allow these antennas to appear on the roof:

1) Make sure that you are outside the house, with your view at the highest level (use PageUp or the mouse controls) and that the roof is visible.

2) Place a suitably sized OMSP on the ground. The height that you choose will depend on how high the roof is, and where on the roof you wish to place the antenna. You may have to experiment a bit. Note that antennas are often not placed right at the peak of a roof, so as to protect them from the weather.

3) Place the antenna on the top of the OMSP, as in the attached picture.

4) You may wish to recolour the OMSP invisible at this point. This is optional, because it is a matter of taste whether you want the OMSP to show through the roof of not. They actually make quite convincing mounting platforms.

5) Now press Control-Shift-C and enter boolProp snapObjectsToGrid false.

6) Also enter move_objects on.

7) If you are using any of the expansion packs you may wish to enter boolProp allow45DegreeAngleOfRotation true which will allow you to rotate the antenna to an 45 degree angle, if desired.

8) Now move the OMSP, with the antenna on it, to a suitable location within the roofed area, as shown in the attached picture.

This procedure is quite a bit easier to do than to describe or read about. Obviously if the roof is enclosing an attic room you will need to place the OMSP in an unused area.
