FEATURES:
This dual polarized yagi was computer designed for the serious Moonbouncer. The very good G/T is a result of
low side and back lobes and the design has been optimized for stacking. This antenna is remarkable in that the stacking
gain for four antennas exceeds 6 dB. Even using a single Horizontal/Vertical relay, you have a moonbounce package
that can outperform larger, linear arrays. Additional relay switching providing 4 different types of signals. Losses from spe-
cial polarity and Faraday rotation virtually disappear. EME reliability approaches 100%. M
power dividers and phasing lines (using Times' new light-weight, low-loss LMR400 and/or LMR600 cable) coupled with 'T'
brace kits, fiberglass H-frame packages, OR2800P Azimuth Rotator, and our New MT-1000 Elevation Motor provide the
building blocks for a whole new generation of high performance EME arrays.

Start by laying out the boom sections using the DIMENSION sheet as a guide. Use 8-32 screws and locknuts to join sections. Sections are swaged to fit each other. 2. Lay out the elements by length and position as shown the DIMENSION sheet. Start with the HORIZONTAL reflector (longest) element and push on a black button insulator to about 1/2”...

Hold the element firmly and start the keeper onto the rod by applying pressure with the push tube. Push the Shaft Retainer until up tight against the button insulator (Locking pliers, lightly clamped up against opposite button insulator will help maintain center reference and keep you from pushing the first Shaft Retainer too far).
