@Dianora Thanks. I'm using DX Engineering coax that has a 10 gauge inner conductor, and the G5rv antenna pictured have came with the correct balun to connect 50 ohm coax, so I think those can probably be ruled out.

J-pole is one of the next things I plan on trying. :blobfoxthumbsup: Just need put together more coax to get to where it'd need to be mounted and acquire some appropriate connectors. (The latter should enable easy construction of a monopole as well, as I have all of the other necessary supplies for it handy. :blobfox: )
