Yep, at some frequency, the EM waves won't know that the coil even exists. :-) -- 73, Cecil, w5dxp.com _________________________________________________________________ Mortgage rates as low as 4.62
Well, a loaded mobile antenna usually has only one coil. With a trapped antenna, the trap closest to the feedpoint is the highest frequency trap. So self-resonance in a trapped antenna is turned int
From: kd4e <kd4e@verizon.net> Could one shift the resonance for use on other bands using a source of switched inductance at the base or perhaps switched or variable capacitance? Before there were scr
Can I add some toploading wires? Here's what I did one time and it worked like a charm. I ran a wire down the inside of the aluminum tubing. The two ends of the wire were attached to a dacron cord ru
From: "Dan Zimmerman N3OX" <n3ox@n3ox.net> Clever! Was it just capacitively coupled to the main radiator or bare wire or what? Yes, it was bare wire of the "silky"variety - very flexible. I installed
The way I keep snakes off my dacron guy ropes and away from my Purple Martin birdhouse is to spiral a small bare wire along the guy ropes and connect those wires to my electric fence. Electric dog f
One side of your dipole is probably already at earth ground, i.e. the coax braid. An RF choke across the antenna feedpoint should snuff out the 60 Hz high voltage while having little effect on the R
