PAR ENDFEDZ® - the original EFHW antenna. Accept no imitations!
Vibroplex acquired the Par EndFedz® antenna product line from LNR Precision in 2019.
The Par EndFedz® End Fed Half-Wave ("EFHW") antennas are like a full length half wave dipole antenna, but with an important difference. The coax connector is at one end of the antenna where it is most needed. These antennas can be mounted horizontally, vertically, or as a sloper. No ground plane or counterpoise is needed. Portable operation could not be easier. Simply hang the far end from a tree-limb - the coax is at the bottom. Hang it from a hotel room window. Use one of our Spiderbeam 40ft fiberglass poles to get it really high in the air. You don't have to run the coax up the pole - tie the far end of the antenna to the top of the pole and feed it from the low end. Supplied end insulators make suspension easy.
UV resistant ABS plastic housing encloses an efficient LC matching network allowing the antenna to be fed with common 50 ohm coaxial cable. All hardware is stainless steel, silver/teflon SO-239 connector. #18 and #22 gauge stranded copperweld radiator wire with our Polystealth jacket is custom made for us in 50,000 ft runs. Tough 100% UV stable polyethylene jacket. 200# breaking strength. One end of the antenna has a #10 solder lug making attachment to the antenna simple and allowing the radiator portion to be replaced if necessary. Power rating for standard single band versions is a conservative 100 watts, high power versions 300 watts and the new ALLBAND-KW 80-10m EFHW is rated for 1 kW ICAS. Ideal for portable operation. Lightweight. The 20 meter version, for example, weighs only 8 ounces. All black construction makes them difficult to see.
No counterpoise necessary. An end-fed half-wave antenna can energize the radiator nearly as well as a center-fed dipole without need of additional counterpoise or other extra conductors. Read a concise explanation written by John Huggins of this here.
