Do you have a balcony? I’m in an apartment, but have a balcony. I just ran LMR400 (several) and put my antennas out there, lol. I figured it was better to ask for forgiveness than pernission.
Landlord did ask what they were and I explained amateur radio and GMRS. (I used angle telling her it’d still work if power and all else lost, which would as I have backup power.) She thought it was neat and even asked if I could setup some wireless bridges on rooftop (two buildings here) for their IP cameras. Easy peasy! Hoping to get brownie points and maybe sweet talk her into letting me set my antennas up there, lol. I’d put them in center roof, where can’t be seen from ground, so nobody could see, else might be seen as “tenant favoritism”.
Even though, my landlord loves me, anyway. Mainly because I’m a veteran and she loves all veterans.
