The upper white section of the tower is actually a plexiglass radome, concealing various microwave and UHF radio antennas.
CARTWHEEL and its cousins were decommissioned around 1990. Most of the towers, mainly atop mountains in remote areas, were demolished or left to rot. However, CARTWHEEL and CORKSCREW (on a mountain near the Appalachian trail in central Maryland) have been maintained in good condition, now repurposed by the FAA.

If I remember correctly you already posted one of the other towers of this microwave network. Wasn`t that the one featuring these large horn antennas below and 4G/5G dishes on top?
@[email protected] That was a different network. The horns and microwave dishes on that tower were disused, and the tower repurposed as a cell site.

Ah ok, different network., rremember. As you mentioned thíngs going unnoticed in plain sight. Everybody passing by the Russian embassy to the UN in Vienna could see 4 large dishes on top. Nobody cared what they might be doing there for years .
Late in 2022 we shot the roof with zooms & sent a drone up. Voilà: a full blown #SIGiNT station with a dozen dishes. And the NSA watching them from their "stateroom" hut above the nearby US embassy to the UN.

And meanwhile we have sort of re-engineered three of these four-meter dishes and identified their targets. All three are C-band dishes and there are not that many C-band sats around any more in the segment from Greenwich to 15°.
Posted a thread on this lately, always fediverse first, and I'm currently doing a longread for a magazine here.
tl;dr: They are collecting signals intelligence mainly for their African putsch politics

@harkank Extremely interesting.
Are these receive-only (have you detected any signals coming out of them)?

None of these 3 large dishes is active. Same with dish 4 in the back, this one is for the Ku band. Dish 1,2 and 4 are equipped with skew angle gear & motors to squint into downlinks.
C-Band modules - LNCs, filters & c - are all from Nortel Canada. The Ku band modules are from Swedish Microwave.
Vienna is by far the largest and one of the few remaining #SIGINT stations in EU on Russki embassies.
Tech staffers were all kicked out except here
