Default Cobwebb Homebrew

Hi Richard

I have a manual tuner and two auto tuners that I have used and it makes no
difference to improve the received signal. I have also used two different
radios with the same outcome.
I'm wondering if the G5RV is to close and is causing this or if the square
10"x10" mounting plat that I have used in the centre of the Cobwebb might be
causing the problem.

The G5RV is at the same height as the homebrew Cobwebb and they are about
15ft apart. All other bands do not sharply drop off like 28MHz does on
receive signals.

Thanks

I have turned it by hand, there is some difference in signal but not much.
The Ariel is 20ft off the ground,, the same as the G5RV.
It doesn't seem to be working right. But I'm not sure how the original
worked.


Hi Barrett,

That is line of sight, easily. As you suspect, you should hear your
friends. Your turning it is OK. Your SWR readings would suggest your
line is OK, your antenna is OK. Aside from using a manual tuner (you
say nothing to my question there), that leaves the receiver as being
suspect.
