FEATURES
The 2M12 features the latest computer techniques for optimization of pattern and gain.
Clean patterns allow you to hear more and interfere less. Clean patterns are essential for
stacking. The 2M12 is ideal for stacking in either polarization. Two 2M12's side by side vertically
polarized are a dynamite FM DX package and 4 or more are perfect for long haul tropo DXing
or moonbounce.
Structurally the 2M12 is sturdy and clean, requiring no boom support. Elements are 3/16"
6061-T6 aluminum rod mounted through the boom on UV stabilized "button" insulators. The
boom is a full 1-1/2 inch diameter in the middle tapering through two 1-1/4 inch sections to stiff 1
inch tips. The heart of the 2M12 is the unique Driven Element Module: connectors are O-ring
sealed to the CNC machined block and balun connectors feature triple O-ring seals. Internal
module connections are sealed in a space-age silicone gel (with nearly 4 times the dielectric
strength of air) to enhance power handling. The 2M12: superior performance, long term electrical
and mechanical integrity. Options include power dividers, phasing lines `H' frames and rotators.
