Those kinds of power lines usually don't mess with our gear, but they can. Just do a range check at the site, with the engine off and another with the engine running. If it range checks ok, you'll probibly be ok with the towers. If you do get a really short range check, you can try calling the power company. They will often try to stop whatever is generating the signal, since it usually means some of their equipment is out of adjustment anyway.

The space sounds small, but if you follow your plan and get started at the club, you'll be able to get a much better feel for the amount of space you need after a few flights.

Good luck!
