New Product Spotlight: Par EndFedz QRP Monoband End Fed Half Wave Antennas

DX Engineering has proudly carried finely constructed, proven, and highly portable Par EndFedz End Fed Half Wave (EFHW) Antennas for several years. Besides selling these popular antennas made for worry-free Field Day, POTA, and SOTA operating, DX Engineering team members—the folks who answer your amateur radio questions when you call—rely on Par EndFedz antennas for their successful outdoor excursions.

DX Engineering customer sales/technical support specialist and OnAllBands blogger Troy, KE8DRR, has taken along a Par EndFedz EFT-102040 (40/20/10M) for low-powering operating (25W SSB/CW) on his outdoor adventures. The same model was noted by blogger Thomas Witherspoon, K4SWL, in his article, “How to Choose the Right Resonant HF Field Antenna.”

Scott Jones, N3RA, DX Engineering sales manager, recommended the EF-10 model (100W SSB/CW, 50W AM/DIG) in this article on upgrading your antennas for maximum results on 10 meters.

Then there are the five-star reviews from satisfied customers. This one is representative of the general sentiment regarding the Par EndFedz EFHW:

Five Stars: (EFT-102040): “I am absolutely in love with this antenna. It’s compact and lightweight, the choke is integrated into a wire winder, and it is made from quality components that should last me years and years. It was beyond simple to tune (I trimmed it a whopping 2 inches) and had a sub-1.5 SWR match across 40 meters, with under 1.8 on 10 and 20. Paired with my Xiegu X6100 it’s a SOTA/POTA monster.”

We also highly recommend taking a few minutes to read “Feeding End-Fed Antennas” and “Little Pistol Low-Band Antennas” (which references the Par EndFedz 80-10M EF-ALLBANDKW), by Ward Silver, N0AX. 

About Par EndFedz

Vibroplex acquired the Par EndFedz product line from LNR Precision in 2019. Vibroplex says the Par EndFedz EFHW 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.”

Further, you can use a telescoping fiberglass mast to get the antenna really high in the air. Stealth operation in CC&R and HOA antenna-restricted locations is simplified. The monoband models’ all black construction makes them difficult to see.

Par EndFedz antennas feature:

  • 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
  • Stainless steel hardware
  • Silver-plated SO-239 connector with PTFE dielectric
  • 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.

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 a 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.”
