[TowerTalk] 80 meter dipole

[Al Kozakiewicz]

FWIW, I have an 80m dipole in an inverted Vee configuration with the apex at the top of the gable end of a one story section of my house, perhaps 18 feet,  and the ends about 4 - 6 feet off the ground.  It's only used for the SS phone contest; with 1500 watts, it does a decent job on QSOs in the eastern US where I live.

At any rate, I consider that antenna to be damn low - maybe/almost NVIS - for 80m.  Regardless, there is a pronounced 2:1 SWR curve with a bandwidth of no more than 150 kHz.  So yeah, the wide bandwidth sounds really suspicious.

HI Hans

It usually works pretty well.  During the WRTC contest last week, I was
able to work a bunch of them with this antenna.  It just puzzles me why
the SWR bandwitch is so wide.  Shouldn't be that way.  73

to make it cover the entire 10 meter.
