If it were me, the antenna would be a few hundred feet away from the equipment.

And the antenna wouldn’t be anything like an antenna, just something that looks like a lawn-chair.

And I’d move it every day or two. And definitely not run it 24h!!!

Could still be found, but good luck.

Hmm, then you need a super-mega-amplifier tacked on to boost the signal over the cable (AFAIK, the frequencies used really like short antenna runs).

So that then means a super-thick faraday cage around the actual device, and probably somewhat noteworthy power consumption (a battery certainly wouldn't be enough).

Probably meant transmitter (antennae + encoder/decoder) separated from actual BTS hardware & operatives.

So after counter-side finds your camouflaged BTS, it is only disposable and relatively cheap part and doesn’t lead to whole operation uncover.

That probe part then would connect to starbucks wi-fi and interact with BTS software somewhere far from physical location, so you can’t quickly trace channel between probe and spy team.

Doh. I see, of course.

Yeah, I'd gotten it in my head the BTS (TXCO) and the probe equipment needed to be super close together...
