Rated at 10 kW maximum input, each bay consists of a Penetrator-style radiating element with a 1-5\/8” shunt feed line. Each JMPC is factory tuned to any frequency in the FM Band II (87.5 - 108 MHz) range on a tower structure that bests simulates the customer’s actual tower. Multiple frequency design is also available. The true circular polarization of the JMPC antenna offers excellent performance for HD Radio, stereo and SCA operation. Typical VSWR is 1.1:1 ± 200 kHz.\u003c\/p\u003e\n\u003cp style=\"text-align: justify;\"\u003e \u003c\/p\u003e\n\u003cp style=\"text-align: justify;\"\u003eRadomes\u003c\/p\u003e\n\u003cp style=\"text-align: justify;\"\u003eDeicers\u003c\/p\u003e\n\u003cp style=\"text-align: justify;\"\u003eFCC Directionalization\u003c\/p\u003e\n\u003cp style=\"text-align: justify;\"\u003eReduced RF Arrays\u003c\/p\u003e\n\u003cp style=\"text-align: justify;\"\u003ePattern Measurement Study\u003c\/p\u003e\n\u003cp style=\"text-align: justify;\"\u003eCustom Mounting Brackets\u003c\/p\u003e\n\u003cp style=\"text-align: justify;\"\u003eElectrical Beam Tilt\u003c\/p\u003e\n\u003cp style=\"text-align: justify;\"\u003eNull Fill\u003c\/p\u003e\n\u003cp style=\"text-align: justify;\"\u003eMulti Frequencies\u003c\/p\u003e\n\u003cp style=\"text-align: justify;\"\u003e \u003c\/p\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe JMPC 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 JMPC 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 JMPC antenna system.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eNotes:\u003c\/h2\u003e\n\u003cp\u003e1.
