The next
step was to get an efficient 160 meter antenna up. My plan was to start
with the 80 meter vertical and build on it. I got the 160 Meter
antenna tuned and up the week after the ARRL 160 meter contest. Go
figure.
I've installed a vacuum relay at the top of the antenna which is
remotely controlled from the shack. It switches in or out
another approximately 65 feet of wire to form an inverted L for 160.
So far, the horizontal part of the "L" droops down to a height of 20 ft
and zigzags a bit for the last 20 feet.
I now have about 45 feet of the horizontal end of the antenna up much
higher secured to new tower and and then over to a tree. My
SteppIR DB-18E on the new tower provides capacitive top loading.
By changing the frequency of the SteppIR I can tune the 160 meter
antenna from 1.8 to 1.9 MHz. making the antenna usable across the parts
of the band I use.
This antenna works fairly well. I am competitive in DX pile ups and met my
goal for this 160 season and finished my top band DXCC. With
the cards in hand the ARRL awarded me 160M DXCC.
