HF Loop Antenna Wire Kits (160-10 meters)
Full Wave Loop Antenna Wire Kit for vertical or horizontal loops (square, rectangle or delta shaped) from 160 meters to 10 meter. Includes end insulators, #14 Insulated stranded copper wire and spade lugs for attachment to an optional balun
Insulators are a very stealthy, strong, 4 PVC, 2 1/4" long. 1" wide. 1 1/8" hole separation wire antenna insulators and may be black, gray or white depending upon inventory.
Typical size id 1005/F(MHz) and cut for lowest frequency in band segment.
For multi-band capability use 4:1 balun such as our Bullet-4BEB-500/1500 or CB-4-1500EB/5000EB with a feed line choke below it or best bet is to use the Hybird 4:1 + 1:1 balun, CB-4-1-1500. For single band use a 2:1 balun such as a Bullet-2B-500/1500 or CB-2-1500/5000EB. with a feed line choke below it or the hybrid CB-2-1-1500EB with built in 2:1 and 1:1 balun.

Baluns are used to connect balanced antennas to unbalanced transmission lines (Coaxial cable) and Ununs are used to connect unbalanced transmission lines to unbalanced transmission lines or unbalanced antennas (e.g. verticals). In the case of 1:1 baluns the input is usually an unbalanced coax cable and the output load is a two terminal balanced load like an antenna. Ununs are also called line isolators, feed line chokes, and 1:1 coaxial baluns (incorrectly). 1:1 Baluns and ununs stop common mode currents (flowing on the outside of the coax braid due to skin effect) when they are located at the antenna feedpoint. They can also be used as “line isolators/chokes” anywhere along the cable to suppress flow of induced RF (antenna near field radiation and neighborhood noise pickup) which helps suppress RFI into the radio receiver/transmitter. For best results, put one at the antenna feed point connection, and one at the radio room entrance, and for difficult common mode current cases, one every 1/4 wavelength along the antenna feed line. For low (below 3 MHz) frequencies, use two 5 bead baluns in series to double the choking impedance or order the 10 bead or 15 bead version for higher choking power.
