Perfect for making inexpensive ham radio dipole or inverted Vee antennas! Works great for Shortwave Antennas and Prepper Antennas. These are also good for balloon launched vertical antennas for visibility on the antenna wire, and they don't weigh a lot for the payload lift. Durable, use them over and over.
Keep 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.
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.
