You're definitely in the gray area. But, he has no right stealing it until he gets approval from the FCC to deny you access. So you got him on that. I would give the police your FCC petition and stuff also. I'd give it a 50/50 chance of being allowed on that front porch thing.
Waaaaaaay back in the day (ok a few years ago). We lived in an apartment. What sucked was we didnt have a private balcony, just a common one that had the steps to the upper floors and stuff. Well this was before we knew about otard, so we drilled that sucker right into the balcony and ran the wire all the way around the apartment. Even dug a trench out and everything. It was a top notch install. We caulked the coax against the siding to hide it. It worked ALL YEAR. Then during the summer, the jackasses stole it and ripped our wire down. We went to get it back, and their like "no dishes". The funny thing is, they had a dish up to get several pay channels and redistribute them to us with the local hijack cable co. They said "our roof, we can do what we want".
So then we made this slide rail thing that would slide out the window opening whenever we wanted to watch tv. it was pointed correctly, just had to slide it. Well, they gave our friends 14 days to take it down (even though it wasnt outside) or eviction. Nuts.
FINAL PLAN. We lived about 100' from a wooded area that was between two apartment complexes. It was like a drainage area. Well, we reforested the area with our own 6"x6"x16' pole and 1/2ton of concrete.
Stuck the dish on that (previously it was a 4x4x8, but some jerk kid knocked the pole over and stole the dish). Then we trenched the wire over to our apartment. It was hard, had to drive a pipe under a concrete walkway and run the wire through, but we got it done. We also shared the dish with our upstairs neighbors cuz they couldnt stand the cable co either. BTW this was a college town and the whole building was college kids. Thats probably why noone cared about the 4 crazies digging a huge hole out in the woods.
The dish was nice and hidden by trees and during the summer 6' of weeds grew around it so there was no way even to get to it. We had to do a little trimming to get a good LOS but it worked. I bet that pole is still there.
So, if you have some woods by your rental, I suggest putting the dish in there
