by Yukon John,
It was time for me to get on 160 meters.
I decided a full wavelength on 80 meters (254 feet)
which yields a half-wave on 160 meters would be enough wire for me to get
tangled up in, or trip over several times, while erecting, hi hi! Oh, did
I mention it will probably be 40 below zero with howling winds as well?
But this is just half of the fun.....the ground system
will have to be elaborate if I'm to achieve success with this
antenna. I'll use a mesh screen and all the scrap wire I can muster
up for the ground system.
So, I'm all set, and when winter rolls around I'll give this beauty a try! I plan to be on for ARRL phone contests (SS, 160 Meter and 10 Meter from "up here") and perhaps some PSK-31 activity as well.
Instead of using the mast as the
"vertical radiator", set the coil about 2 feet out and away
from the mast at the top and use wire as the vertical radiator instead of
the mast and then drop and terminate the vertical radiator wire
in the PVC coupling where it is terminated with the coax
center. (remember to add more wire if wire is used rather
than the mast). The wire can be pulled out and away at an angle
from the mast. This is probably the approach I'll use depending on
available space. I'll also use my drive on mast base
I'm amazed at what I'm
doing with a piece of wire! With some simple modifications while
operating from the Dominican Republic, this is now a tried and proven
winner for me.

(I'm only lacking 3 or 4 states for WAS on 20 and 17m and about 12 on 40m in the first 3 weeks of operating)
