The 222XP30 is the dual polarized version of the famed 222-5WL 15 element Yagi. 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 1/4 wave length 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 dynamite DX package for FM and SSB and 4 or more are perfect for long haul tropo DXing or moonbounce. The 222XP30 allows you to experience the radio spectrum’s best tropo frequency without bustin’ your mast or your budget! Structurally the 222XP30 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 tapering through two 1-1/4 inch sections to stiff 1 and 3/4 inch tips. 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.
