FEATURES:
The 345CP38 is high performance circular polarized antenna with a remarkably clean pattern. The pattern is important in
order to match the antenna's noise temperature with modern low noise preamps. This antenna is ideal for satellite work
but is also excellent for terrestrial uses like long haul tropo communications.
The CNC machined driven element module is O-ring sealed and weather tight for low maintenance and long-term
peak performance. Internal connected are encapsulated in a space-age silicone gel that seals out moisture and improves
power handling. The 3/16" 6061-T6 rod elements are centered on the boom to minimize interaction and maintain good
ellipticity. Insulators are UV stabilized and locked in place with stainless keepers. Rugged construction, uncompromising
performance for the boom length: that's the M

  • Page 2 345CP38 ASSEMBLY MANUAL TOOL REQUIRED FOR ASSEMBLY: screwdriver, 11/32 nut driver or wrench, 7/16” and 1/2” socket or end wrenches, measuring tape. 1. Assemble the boom using 8-32 screws and locknuts to join sections. ( SEE BOOM LAYOUT PAGE). ASSEMBLING THE HORIZONTAL ELEMENTS 2.
  • Page 3 THIS COMPLETES THE ANTENNA ASSEMBLY. INSTALLATION TIPS 1. The 345CP38 is a circular polarized antenna and creates a field in all planes or polarities. Performance DETERIORATES SIGNIFICANTLY if it is mounted on a metal (conductive) mast or crossboom. A mast or crossboom of any NON-CONDUCTIVE material must be used.
