This antenna uses the same basic design as the JAMPRO PENETRATOR series of side-mount antennas, which set the industry standard for FM antennas. By using an external and non-pressurized feed system, manufacturing costs are kept to a minimum. Each bay is fed with flexible cable. Configurations with two or more bays are fed through a power divider and cable system that has a 7\/8\" EIA flange input (female). The antenna elements are constructed of high strength marine brass.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: justify;\"\u003e \u003c\/p\u003e\n\u003cp\u003ePower rating 4kW maximum\u003c\/p\u003e\n\u003cp\u003eOutstanding VSWR without field tuning\u003c\/p\u003e\n\u003cp\u003eAvailable for 88-108 MHz\u003c\/p\u003e\n\u003cp\u003eElectrical deicers available\u003c\/p\u003e\n\u003cp\u003eVSWR 1.1:1 +\/- 150 kHz\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"JAMPRO","offers":[{"title":"JLLP-2 2 BAYS","offer_id":36322872787098,"sku":"","price":0.0,"currency_code":"USD","in_stock":true},{"title":"JLLP-4 4 BAYS","offer_id":36322872819866,"sku":"","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0422\/1291\/7402\/products\/JLLP__88790.jpg?v=1602002266"},{"product_id":"jampro-jmpc-medium-power-circular-penetrator","title":"JAMPRO JMPC – Medium Power Circular Penetrator","description":"\u003ch1 style=\"text-align: justify;\"\u003e\u003cspan style=\"color: #000000;\"\u003eJMPC – Medium Power Circular Penetrator\u003c\/span\u003e\u003c\/h1\u003e\n\u003cp style=\"text-align: justify;\"\u003e \u003c\/p\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe JAMPRO JMPC antenna is the medium-power version of the Penetrator antenna, which has become an industry standard for quality and performance.
