[TowerTalk] 40 m Dipole question.

[Lizeth Norman]

Hi all!
I'm helping a friend set up a 40 m dipole on his tower. It hangs at
approximately 30ft. The dipole is in a flat top configuration. There is
some droop on the ends, but not too much. We have tried it at the 33' per
side length as well as 30' per side. Neither gives reasonable swr. Both
show 3:1 +. The cable is tested good (into my bird load) at 100 watts.
Tried using a balun, and not using a balun. The tower is heavily grounded.
Any ideas to try?
