The 2M5-440XP is ideal for linking repeaters and remote bases utilizing both 2 meters and 440MHz. Elements are cross polarized to avoid the severe performance compromises on 440 Mhz common to other dual band antennas that have all elements in the same polarity. The XP also workds well on the OSCAR frequencies and is handy wherever dual band capability and compact size are required. Recently, with PACKET users finding horizontal poliazation better on 2 meteres, it has become even more useful.
Construction is designed for long term mechanical and electrical integrity. The heart of this antenna is CNC-machined driven element block. Connectors are O-Ring sealed and the internal connections are encapsulated in a space-age silicone gel with nearly 4 times the dielectric strength of air. Balun connectors are triple sealed and nut-sealed at the block connectors. Elements are 3/16 6061-T6 alminum rod, centered through the boom on UV stabilized insulator buttons. All hardware except U-bolts is stainless steel (S.S. nuts and lockwashers are supploed for them, too).
