Works great for Dipoles, Inverted Vees, End Fed and Random Wire antennas! Bring your Shortwave receiver to life by making a good antenna.

Use these to insulate the ends of your wires making up your ground plane on elevated vertical antennas.

Slim line construction in Ceramic - Heavy Duty Design.

Insulators are approximately 2-1/2 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.

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. 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.
