JHPC High Power Circular Penetrator Side Mount FM AntennaThe JAMPRO JHPC antenna is the high power version of the PENETRATOR antenna, which has become an industry standard for quality and performance.Each bay consists of a PENETRATOR style radiating element with a 3-1/8 shunt feed line. Each JHPC is factory tuned to any frequency in the FM Band II (87.5 -108 MHz) range on a tower structure that bests simulates the customers actual tower. Multiple frequency design is also available. The true circular polarization of the JHPC antenna offers excellent performance for HD Radio, stereo and SCA operation. Typical VSWR is 1.2:1 200 kHz. (Optional 1.1:1)..The JHPC antenna is constructed of the highest quality marine brass and copper. A hot dipped galvanized steel mounting bracket for utmost grounding supports each bay. Standard round leg mounting brackets for uniform face towers are included with each antenna. Silver plated inner conductor connectors are used throughout for maximum contact life and minimum power loss.Each JHPC antenna is DC grounded at every bay for maximum lightning protection. This rugged mechanical construction and mounting ensure the long life and outstanding performance of each JHPC antenna system.
