All national and local cellular carriers are looking to get access to these valuable spaces to put up their 5G antennas.

Antenna to get over the air channels (OTA).

You may want a different roof or antenna for a storm radio. 

So, you have more sources to target for a judgement if things go awry.(3)  The couple who want a 2-3 year lease raises my antennae a bit. 

When I finally had somewhat of a cell signal, I switched to a hotspot - even installed an outdoor antenna to increase reception for the hotspot.  

@Debasish BhattacharjeeThe lawn and DISH antenna are lease violations that will cost you money.

They are more expensive but worth it to me.After buying a house that was wrapped twice in coax, I decided that I add a standard television antennae in the attic and run the coax down myself - usually into a crawl space or basement where I can connect it to a splitter and pre-wire to each room even if it is up from the floor.  

@Bill Gulley Ah, also an interesting perspective.To address some questions:- It's a rooftop antenna (not ground)- Technological need: They've mentioned this is part of a network redesign (and actually probably related to a merger/partnership on their end).

In rural areas a single site can potentially cover 10 miles, but again each site is unique and also explains why carriers spend a lot upfront to position their antennas to provide maximum coverage, but also avoid interference with others on the tower.We build towers nationwide and also consult with property owners who have existing sites (tower/rooftop antennas) to help negotiate and maximize revenues through site management.
