If you are setting up a base station, your landlord or HOA may have restrictions on the antenna size. There are no permissions or license required in the U.S. from the FCC assuming you are using unmodified CB radios. Keep the antenna and coax cable away from other equipment if you can, to avoid interference that results in neighbors complaining about you.
Technical:
Look for ARRL sites that describe how to properly install and ground your antenna as well as different antenna types. The same knowledge for ham operators using the HF bands will apply to CB radio (26-27Mhz). HN is not a sufficient platform to give you all the steps you would need. You will need an antenna, SWR meter (standing wave ratio) to tune your antenna, coax cable, antenna mast, grounding connection (new or existing building ground). An all-around decent omni-directional antenna would be a 5/8's wave ground plane. 1/2 wave are more plentiful but less effective for what you are doing. The ARRL sites will give you information on how to do all of these things. You could also find a local ham radio club that will have people knowledgeable in this area. They may try to get you into HAM radio and that does require a license.
There are CB radio base station transmitters. The selection is smaller today than in the 70s/80s. You can find equipment on Amazon, just don't trust the positive reviews in my opinion. Try to find something that has both AM and SSB (LSB USB) should you some day want to talk to other countries using skip conditions.
You will find truckers and maybe some locals on channels 17 and 19. Channel 9 if for emergencies but may not have anyone responding. Happy to add more later, but I have to step away for a bit.
