[Elecraft] OT: Antenna ideas for a cheap ham

[Goldtr8 (KD8NNU)]

I use a cobweb at 40ft and it works real well for me also.   It’s a good 
multiband antenna.

I don't have a tower but I am using a 10-20m cobweb antenna in my
attic. It's non-directional and feeds with a single coax. It gets out
pretty well on all five bands. Recently worked aZL station on 17m with
less than 2 watts (this is the requisite anecdotal information... but
true.) I'd love to try it on an 80 ft tower...

I'm using the G3TXQ version with single-wire elements. I originally
trimmed it to freq using a (cheap) noise bridge but a graphical
antenna analyzer would be nice and easy.
