Par EndFedz® End Fed Half Wave Antennas

Par EndFedz® Antennas are low-power End Fed Half Wave (EFHW) antennas with the match box coax connection at the end of the wire, for convenient and quick stealth portable operations. These single-band and multi-band antennas can be mounted horizontally, vertically, or as a sloper. No ground plane or counterpoise is needed so portable operation could not be easier. Simply hang the far end from a tree limb or send the wire out hotel room window or balcony. You can use a telescoping fiberglass mast to get the antenna really high in the air and the supplied end insulators the installation easy. Stealth operation in CC&R and HOA antenna restricted locations is simplified. The mono-band models' all black construction makes them difficult to see.

Each Par EndFedz® features a UV resistant ABS plastic housing with support rope attachment hole that encloses an efficient matching network to allow the antenna to be fed with standard 50 ohm coaxial cable with PL-259. All hardware is stainless steel and the SO-239 connector is silver plated with PTFE dielectric. The antenna wires are either 18 or 26 AWG stranded Copperweld® with 200 pound breaking strength and a tough, 100% UV stable black polyethylene jacket. One end of the antenna wire has a #10 solder lug making attachment to the matching network feedpoint simple and easily replaceable, if necessary. Standard single and multi-band versions handle 100 or 200 watts and high power versions handle 300 watts. Lightweight QRP PolyStealth models handle 25 watts and are ideal for portable operation because they are lightweight; the MKII model weighs only 8 ounces and the Trail Friendly model weighs only 3.5 oz. Par EndFedz® Antennas require no counterpoise or extra conductors.

The manufacturer refers to these antennas as "End Fed Dipoles" based upon the assertion that a "half wave radiator is a dipole." This is a variant of the classic definition of a dipole that is center-fed antenna with two radiating legs running in opposite directions from the feedpoint. Additional claims about the EFHW state that end feeding a half wave "can energize the radiator nearly as well as a center-fed."
