2m Band HO Loop Antenna

For quick and easy communications up to 200 miles or more, the new 2M HO LOOP provides an omnidirectional, HORIZONTALLY polarized signal ideal for mobile and base operations on sideband and CW. Horizontal polarity permits a single HO loop to pick up 4+dB of ground gain that verticals can't. As with most horizontally polarized antennas, performance improves dramatically with height above ground. By stacking two HO LOOPS, another big gain jump occurs (see pattern and note great reduction of high angle lobes). HO LOOPS do not need a counterpoise, so mounting options are simplified. Mounting 18" high, in the middle of a vehicle roof produces 2 dBd gain in a ball pattern upward for LEO satellite and modest terrestrial operation.

Physically, the 2M HO LOOP is a 11.25" square loop, fabricated from two 3/8" dia. aluminum tubes to minimize losses. The sealed feed block provides weather protection with minimum wind drag. The heart of this unique design is the shorted stub matching to a 50 ohm coax feedline. Mounting is via a single 3/8" hole (standard mobile mounting hardware size).

For more performance, try the HO LOOP-STACK PACKAGE: 2 HO LOOPS, phasing lines, "T" junction block, upper and lower 1/2 " and 5/8" mast sections. For easy base-station installation use the optinal wall / mast mounting bracket and U-bolts. For a powerful mobile signal, stack and array of HO LOOPs on our optional "BIG FOOT", mag-mount ( shown above). Use the optional 5" magnet and 18" mast for single band mobile operation.
