KL7JR Indoor Bent Vertical Dipole 10-20 Meters
Okay now that I've
relocated back to Alaska and living on the top floor (14 th) of a
high-rise apartment, I can't put up any exterior antennas. I guess I
should just limit myself to work mobile or portable then? Not!
Hey, what ham would'nt want to take advantage of being 150
feet above ground, hi hi!
Total length of each leg of the antenna is 17 feet long
(each 2 inch diameter coil, one per leg, measures about 14 feet of #14
solid insulated wire). I find the solid wire easier to work with and form
the coils. I made the coils larger to better utilize the space I had (hmmm
will that work?). My windows were of the new high efficiency plastic style
which afforded me a lot of glass and not much metal framing to worry about
interference. My LDG-100 auto tuner easily tuned 10, 12, 15, 17 and 20
meters quickly, so that was a good sign for me. Band conditions were
terrible the past 3 weekends up here (March 2009) but I managed to work
Oregon, Washington, California, Idaho, Montana, New Jersey and Ontario,
Canada with S5 or better reports each way on 20 meters. I set my output
power to 50 watts so as not to advertise to the neighbors what I was up
to! When the bands improve, I will go QRP.
Editors note: Try is outside on a mast with the legs vertical!
Let us know how it works for you!
