No antenna will work across the full 75/80 meter band with low enough

centered on 3750 KHz to the band edges is excessive. If you cut the
antenna for 3.9 MHz it most likely will not load up well below 3.7 MHz.
A tuner is required!! PERIOD.

For comparison, the bandwidth range on 20 meters centered on 14.175 is
only +/- 2.4%

Don't jump on condemning the antenna too soon. Do some more research and
ask more questions regarding 75/80 meters broadband antennas and what
"broadband" means.


Be kind folks! You're all correct, but don't bash the guy's head in.


75 and 80 meters is indeed quite a range to cover, especially when it
is actually 85 to 75 meters in wl.

I'd buy a tuner that will handle open wire feed, lose the 4:1 balun,
and get on the air.
