I realize I'm short on theory and long on dumb novice questions. Also, I apologize for posting a second time before even finishing the first post, but this is another antenna option I'm wondering about.
I'm wondering if I might be able to use an existing 35' heavy duty steel (?) flagpole as an antenna, especially for 10 meters, if an antenna tuner is used. It is mounted with four 1" dia. bolts through a 1.5' square steel base into a 3 x 3 x 3 ft. concrete base that may or may not have footings beneath ground surface. The bolts run through about 1/2"- 4 x4" steel plates, making the steel base of the flagpole gapped from the concrete, except at the corners, by 1/2".
Is concrete a tolerable insulator? How about when wet? I wondered about coating the concrete with a rubber sealant or some kind of rubber gaskets with the bolts and plates, but am a little hesitant to unbolt it lest the concrete crack.
I thought about mounting an antenna at the top, but its awfully close to power lines, and I'm concerned it could blow off the flagpole in a fierce wind.
Suggestions? Or is it an idea only worth abandoning?
Thanks. Will catch up with you all. Glad you're out there.
