I am in a subdivision, thankfully no HOA BS to deal with, but seriously limited by the need to not be conspicuous/obvious. Inverted V over a chainlink fence is one thing I'll try. I'd also like to construct a 35' vertical basically a monopole insulated from ground. Where to put it is my issue.
As for now, I'm working on an inverted V and can hopefully get this thing up before much longer. I'm probably limited to 15' at the most on this one.
Other than that, I'm going to experiment with odd ideas and see what I get with them. It will be odd transmitting from the midwest!
