FEATURES:

The 146CP8 is a practical sized, yet 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.
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 to minimize interaction and maintain good ellipticity. Insu-
lators are UV stabilized and locked in place with stainless keepers. Rugged construction, uncompromising performance

  • Page 2 146CP8 ASSEMBLY MANUAL TOOL REQUIRED FOR ASSEMBLY: screwdriver, 11/32 nut driver or wrench, 7/16” and1/2” socket or end wrenches, measuring tape. ASSEMBLING THE HORIZONTAL ELEMENTS 1. Lay out the elements by “HORIZONTAL” length and position as shown the DIMENSION SHEET. Start with the reflector (longest) element.
  • Page 3 146CP8 ASSEMBLY MANUAL 9. Before installing the Baluns and Matching / Phasing Harness, thread 3/8” SEAL NUTS fully onto all connectors, with the black Neoprene face of the nuts facing out. Attach Baluns and Phasing lines to the gently using a Driven Element Blocks and Junction Block as shown on the Dwg.
  • Page 4 146CP8 INSTALLATION TIPS & HINTS 1. The 146CP8 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. Fiberglass is the prime choice for its strength and weather resistance.
