FEATURES:

This is the latest addition to the high performance M

family of weak signal antennas. As the name implies, the 432-12EME has been

specifically designed as a potent yet compact

EME

(Moon bounce)array. It is ideal for home and trips (DXpeditions). Its light weight

and rear mount capabilities keep phasing lines short and mounting simple. When used only for terrestrial and stacked 4 high the
azimuth beamwidth is still 26 degrees, but the gain is over 20 dBd! EME CW or JT65B, you’ll be amazed!

POLARITY DIVERSITY is possible by adding 4 more in the opposite polarity to a slightly extended “H” frame. Note also that it

covers the satellite band! What a nice extra.

Construction is classic M

for long term electrical and mechanical integrity. Elements are 3/16” 6061-T6 rod, mounted through

the boom on UV stabilized insulators and locked in place with stainless steel shaft retainers. The driven element module is CNC
machined and all connectors O-ring sealed. Internal connections are encapsulated in a space-age silicone gel. Balun connectors are
triple-sealed to the coax. Our “H” frame used for the above specs is 2” x .125 x 60” cross boom and 2” x .065 x 60” risers. Ask about
special configurations for your special project. And don’t forget we make the MT1000 elevation rotator. It easily handles 4X2M9SSB

AND

4X or 8X 432-12EME’s. WHAT A KILLER SYSTEM!
