Hi @WA4OSH, and welcome to SatNOGS! I’m in the same boat you are: I’m in a townhouse and don’t have the space to put up a rotator. That isn’t stopping me from slowly building one, though…
I’m thinking of contacting either a local ham club or a high school to see if some space can be arranged on a rooftop.
There are folks around who have no-rotator setups, often with vertical antennas – some are even running rotators indoors. I’ve had varying luck mounting the rabbit-ears that come with the latest RTL-SDR version on the inside of a 3rd story window…for some stronger satellites, I can still pick up a signal (though not necessarily well enough to do any data decoding). I suspect that a better antenna would pick up more, even inside.
Hopefully that gives you some ideas!
