Our 6M HO Loop is the result of a continued development of reduced size, omni-directional horizontally polarized loop-style antennas. This new design is easy to match in any situation. Performance is better than anything in its class and its design makes it immune to nearly all weather conditions.Power handling is often a problem with small loops but this design can handle 800 watts with ease and a stacked pair can easily handle 1.5kW. The patterns contained in the manual will give you a good idea of how well the 6M HO Loop will perform in your system.
As with all horizontally polarized antennas, performance is usually tied to height above ground but even at ten feet the HO Loop yields an amazing 5.9 dBi at an angle of 27 degrees. Mounted on a vehicle at eleven feet above ground, the gain jumps to 6.3 dBi at 25 degrees. Stacked for base or portable use, twelve foot spacing is optimum. Note that the gain jumps over 3 dB for a stacked pair of these unique antennas, yielding as much as 10.3 dBi!
Physically the HO Loop is 29.5 inches square with a wind area of just 0.1 square foot. The 3/8” diameter tubing keeps it light but plenty rugged for mobile operation. Our precision machined aluminum feed block is sealed and potted with silicon gel for extreme reliability and low loss. The feed block slides on the tubes for frequency adjustment and the shorting bar adjusts for a perfect match into 50 ohm feedline.Two HO Loops can be stacked using a coaxial power divider.
Optional items include our line of lightweight aluminum mobile masts and our “Big-Foot”heavy duty magnetic base. We also offer coaxial power dividers and phasing cables for stacking HO Loops.

Surprisingly good performance for an omnidirectional antenna. Have worked several Es openings in the 1,500 mile range with good signal reports. Sturdy construction and easy assembly. A little tricky to tune, but once done it stays tuned.

I wanted a low profile horizontal polarization antenna for 6M and bought the HO loop. It went together easily. Tuning was a bit awkward though. The aluminum tubes do not move freely through the block due to the bending of the loop when any force is applied. Some form of stabilizer on the loop side by the feedpoint could resolve this. It just took longer than it should to get the loop tuned. I have nothing to compare it to performance wise but I'm looking forward to sporadic E season to give it a good workout.
