NEW M2 - 2M HO LOOP - 2 Meter (144-144 MHz) Loop Horizontal, Omnidirectional. Ideal
for mobile and base operations on side band and CW. 11.25” square loop -- Fabricated from two 3/8 Inch diameter
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. Use a single 3/8 Inch hole (standard mobile
mounting hardware size). Specifications: Frequency Range: 144 - 144.5 MHz Gain,
Typical @ 10 ft: 4 dBd @ 10 degrees Gain,
2 Stacked @ 82" & 132" 8 dBd @ 9 degrees Polarity: Horizontal Omni Impedance: 50 ohms, unbalanced Power Handling: 800 Watts, 1.5 kW for Stack Feed Contector: SO-239 Mounting: 3/8 - 24 Vehicle Mounting Height: 18 Inch or more Stacking Separation: 36 to 50 Inch Wind Area: 0.025 square foot Antenna Weight: 14 oz
PER M2 Antenna website: 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).
