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 support
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.
