M2 Antennas Horizontal Transmit Loop Antennas
M2 Antennas HO LOOP Antennas
M2 Antennas HO LOOP Antennas provide easy SSB, CW and Digital communications out to 200 miles or more. These are great VHF and UHF antennas for the new operator just getting started in either mobile or base weak signal operations. HO LOOP Antennas are the right choice for any operator who wants the convenience of omnidirectional coverage, with the correct polarization, without investing in a rotator and support that is required for Yagi antennas. HO LOOPs transmit and receive horizontally polarized signals that are required for weak signal operation, where verticals are not effective. Horizontal polarity permits HO LOOPs to add upwards of 5dB of ground gain that verticals cannot. As with most horizontally polarized antennas, performance improves dramatically with height above ground, especially on VHF and UHF bands. Physically, the HO LOOP Antennas are square, fabricated from two 3/8 in. diameter aluminum tubes to minimize losses. Their 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 coaxial feedline. They are lightweight and have very low wind area, which makes them ideal for stacking in base or mobile operations. Mounting is via a single 3/8 in. hole that is standard for most mobile hardware, with optional mounting hardware available for base* or mobile installations, as shown. Minimum vehicle mounting height and stacking separation dimensions are displayed in the details for each HO LOOP. Gain figures appear below and in their Instruction Manuals. *NOTE: Mounting of HO-LOOPS on a 1-1/4 to 2 inch mast for base operations requires the optional MSQ-MASTBRKTKIT. Enjoy the thrill of VHF and UHF weak signal operations with M2 Antennas HO LOOP Antennas from DX Engineering! Gain figures for each loop at specific heights above ground for mobile operations. However, loop installations for base operations should be as high above ground as possible, just as though it were a beam (but no rotator required). 50 MHz Gain: Single HO Loop at 11 ft. is 4.2 dBd at 25 deg.; Stack of 2 HO Loops at 40 ft. and 52 ft. is 8.2 dBd at 6 deg. 144 MHz Gain: Single HO Loop at 10 ft. is 4.0 dBd at10 deg.; Stack of 2 HO Loops at 82 in. and 132 in. is 8 dBd at 9 deg. 222 MHz Gain: Single HO Loop at 84 in. is 4.7 dBd at 7 deg.; Stack of 2 HO Loops at 84 in. and 117 in. is 8.2 dBd at 7 deg. 432 MHz Gain: Single HO Loop at 86 in. is 5.0 dBd at 4 deg.; Stack of 2 HO Loops at 84 in. and 100 in. is 8.8 dBd at 4 deg.

M2 Antennas HO LOOP Base Installation Hardware
M2 Antennas HO LOOP Installation Hardware is used to install HO LOOP antennas on a base station mast that is any size from 1-1/4 in. up to 2 in. diameter. MASTBRKTKITs have the brackets, nuts, bolts, cradles and u-bolts to mount HO LOOP antennas onto 1-1/4 in. up to 2 in. base station masts. To install 6M HO LOOP Antennas onto a base mast, be sure to get the MSTSUPMD6M Support Bracket. Add or stack other HO LOOP Antennas on 1/2 in. diameter mobile masts, sold separately, extending above the base mast, for simplified mounting.

M2 Antennas HO LOOP Stacking Kits
M2 Antennas HO LOOP Stacking Kits provide the parts for vertical stacking of two HO LOOP antennas, to achieve an additional 3 dB gain. Stacking two loops at sufficient height above the ground will focus your VHF or UHF horizontally polarized omnidirectional signal toward the horizon, so you can make more contacts with more distant stations! You can expect better long haul tropo range with two HO LOOPS and HO LOOP stacking kits. HO LOOP Stacking Kits contain phasing lines, "T" junction block, upper and lower small mast sections. The HO LOOP Antennas are purchased separately, as are the appropriate base or mobile installation mounts. Get your HO LOOP Stacking Kits form DX Engineering today!
