The Par EndFedz® 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. More Details>>
