Works great for Dipoles, Inverted Vees, End Fed and Random Wire
antennas! Bring your Shortwave receiver to life by making a good
Use these to insulate the ends of your wires making up your ground plane on elevated vertical antennas.
Slim line construction in Nylon - Heavy Duty Design. These are lighter
than our ceramic insulators so if you are using lite weight or thinner
wire they won't drag it down or break it quite so easy.
Insulators are approximately 2-3/8 inches in length with the diameter
about 1 inch. Ribbed construction of the insulator provides increased
surface path to reduce RF leakage. Approximately 3/16 inch hole for
antenna wire. The holes are done to eliminate antenna wire overlap to
help with RF interaction of the antenna and support wire or rope.
Keep some of these insulators, a roll of light weight wire, and some
coax cable together and you are all set to make a handy antenna for
emergency operations, in a time of need for bugging out for your ham rig
or shortwave receiver, or as a camping antenna. Perfect for bug out
bags and shelters with the super light weight design and small size.
Keep some in the camper or RV with some wire and use them for temporary
antennas when parked or camping.
The formula for building dipole antennas is 468/Freq (in MHz) and then
divide by 2 to get each leg length, ie: for 40 meters it would be
something like 468/7.050 for 66.38ft/2 = 33.2 feet per leg. For a
Inverted Vee antenna deduct about 5% from each leg's length.
