I've been setting up a feed for my nearest regional airport (KSWO) and still have to settle on a permanent location for the antenna (a homemade J-pole that works great mounted on my roof at home, not so great leaning against the wall inside my office, where I'd prefer the feed to be). That will probably be resolved in the next week or so.
In the meantime, I've gotten my brother hooked on the idea, but he may be too far away (24 to 28 miles) from his nearest major airports (KOKC and KPWA) to receive the tower or ground comms. His current antenna is a Radio Shack discone antenna (the big one, not the little one they show in their catalog now) that doesn't seem up to the task. It's low (no) gain, so I think he'll benefit from the higher gain of my tuned J-pole. On Wednesday we'll be testing that and a colinear I built.
Assuming that doesn't pan out, it has been suggested that we search for any local "Center" transmitters (I do know the "local" Center freqs at PNC and OKC). Centers would be ZFW for his location, and ZKC for mine. So after all that long-winded intro: where are Center transmitters physically located? Are they necessarily at a local airport or might they be out in the boonies somewhere? I've asked my friend Google repeatly but he's staying mum on the topic.
Thanks in advance for any help!
