Latest News!
 
On August 2, 2010 LnR Precision, Inc.  acquired the popular Par EndFedz line of amateur and SWL antennas. Larry, AE4LD, will be the new owner. Larry is a talented machinist, active amateur, QRPer and will be far better equipped to manufacture and expand the EndFedz line of antennas. In recent  years, PAR has had to resort to only accepting orders in 1 week windows in order to better balance their growing commercial segment and the amateur products. LnR Precision will have much larger manufacturing capabilities and thus amateurs will benefit from much faster order filling. Dale W4OP will be staying on to complete new designs and offering technical assistance to LNR Precision. Amateurs can expect new novel EndFedz models in the near future. "I wish to thank the many thousands of amateurs who have bought EndFedz and whom I think of as friends. I will continue to design/manufacture both commercial and amateur filters and expand our line of commercial and amateur VHF/UHF antenna products and hopefully some really interesting surface mount accessories for HF rigs." -Dale W4OP

Par EndFedz® Product Line

(Patent Pending)

The Par End-Fedz® are a full length half wave dipoles, but with an important difference. The coax connector is at one end of the dipole, 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 up in a hotel window or string it up in the attic. End insulators are supplied making suspension easy.
