HI everyone I have question can a 160 or smaller dipole be bent to fit on a small roof with no problems and will it work well?
Thanks

Hi Rich! Specifics will depend on the folding pattern. SWR may be considerably different from the expected 70-odd ohms. Performance will be impaired; how much, again, depends on the folding pattern. If you have the bad luck to fold it such that the RF cancels out, it might be pretty useless. You could try modeling it in a free version of NEC, or just install it & find out empirically. Personally, I'd consider trying 40 first. Be a lot easier to install, require less bending, and take up less space. My house is roughly 26' x 26', and I think folding an 80M dipole to fit that roof, and still have decent performance, would be tough. But, I've neither modeled nor tried it. Good luck!

I have a 70x110 ft back yard. I found an Inverted L with elevated radials to work well on 160M. I have both WAS and DXCC from Connecticut.
