FEATURES:
The new 222 MHz HO loop provides easy SSB and CW communications out to 200 miles or more. HO LOOPs pro-
duces an omnidirectional, HORIZONTALLY polarized signal ideal for mobile and base operations. Horizontal polarity per-
mits the HO loop to pick up 5+dB of ground gain that verticals can't. As with most horizontally polarized antennas, perfor-
mance improves dramatically with height above ground. By stacking two HO LOOPS, another big gain jump occurs.
Physically, the 222 HO loop is a 7.75" square, size 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 short-
ed stub matching to a 50 ohm coaxial feedline. Mounting is via a single 3/8" hole that is standard for most mobile hard-
ware. For enhanced performance, add a second HO LOOP and STACKING KIT, it has all you need, phasing lines, "T"
junction block, upper and lower 1/2 " and 5/8" mast sections. For easy base-station installation use the optional wall /
mast mounting bracket and U-bolts. For a powerful mobile signal, stack an 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.
