43' Vertical

[KU2C-2]

Jim, In June a put a ZeroFive 43'er up and initially fed it with an SGC tuner at the base ( I live on the water on the Jersey coast and only had about 10 random length radials and one ground rod.)


With the SGC tuner I could operate anywhere from 160 - 6 meters. Unfortunately a nearby lightning strike took out a few diodes in the SGC and I replaced it with a 4:1 balun and used the internal tuner in my K3. Worked fine 80 thru 10, on 160 it was difficult to find a match near 2:1. Similarly on 6 meters - a match was only possible on a narrow band just above 50.1mhz.


From June to early August (WAE weekend) I logged about 120 countries.

Thanks Pete.  What is the feedline?  How long is it?

If you're using any sort of tuner at the base of the vertical, the
feedline is much less important.  It's 50 ohms at the output of the rig,
50 ohms at the input to the tuner, and the SWR on the feedline is 1:1.

It only gets goofy when the feedline is an unfortunate length, the
antenna isn't near 50 ohms, and the tuner is on the other end of the coax.

Sorry, I misunderstood your post -- thought the tuner was in the shack.

Thanks and 73, Jim
