Model No: 222XP40
FEATURES:
The 222XP40 is the hot, new dual polarized Yagi specifically for EME and long haul terrestrial communica-
tions. It is our latest design using computer techniques to allow maximum gain and patterns in both the horizontal
and vertical planes. The vertical elements have been shifted
/4 in front of the horizontal set to allow circular
polarization if needed. This means four possible polarization modes with one antenna! Two antennas stacked are a
great tropo and EME package and four or more are amazing allowing Even small Yagi EME contacts using CW or
JT65B. Structurally the 222XP40 is sturdy and clean. 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 3 sections
tapering through two 1-1/4 inch sections to stiff 1” and a short 3/4 inch front tip. The main ‘N’ connectors are O-ring
sealed to the CNC machined block and 4:1 balun connectors feature triple seals. The internal module connections
are sealed in a space-age silicone gel. See our other accessories including preamps, power dividers and custom
made phasing lines.
SPECIFICATIONS:
XP = cross polarized; H = horizontal; V = vertical; EME = Earth-Moon-Earth; *Subtract 2.14 from dBi for dBd
