Nobody needs to jam anything, a starlink cpe needs to transmit. Try to operate one in xinjiang province, for instance, men with portable spectrum analyzers and guns will come to take it away and arrest you.
With a horn antenna tuned to the right band and a portable spectrum analyzer, finding a starlink, kuiper or oneweb cpe will not be technically difficult.
Also worth remembering that this kind of equipment, beyond being available to militaries, is also routinely in use by governments everywhere to enforce local RF regulations. Even in times of perfect calm, if you start illegally transmitting and disrupting legit radio activity, you can expect the local equivalent of FCC to quickly track you down.
Ku and mid ka, high ka band spectrum analyzers are no longer a $40,000 item anymore. I'm pretty confident I could put together a (starlink, kuiper, oneweb) locating kit for under $10k USD. The knowledge to run a spectrum analyzer just to locate on class of equipment could be taught to any moderately educated local police in one day.
Not much is using these bands anyway, especially in places like Iraq. Wouldn't it be even simpler to skip the spectrum analyzer and sweep the area with high-gain antennas tuned for these bands, the fox-hunting way?
