{"product_id":"spt-500","title":"SPT-500, VERTICAL, 10\/12, PENETRATOR, 1.5kW","description":"This fantastic true full-size 5\/8 Wave 10 \/ 12 Meter vertical antenna from Hy-Gain was a legend in the 70’s . . . now it’s back to prove its legendary status once again! A Full-size radiator with lower radiation angle concentrates power closer to the ground, where you want it. Measures 22 foot, 9.5 inches. Larger diameter, heavy wall ply-tubular construction makes the new Super-Penetrator™ the absolute top omnidirectional antenna around! Four full-length radials and special machine-formed brackets give extra talk-power and overall strength. Electrical performance has been increased to a new standard by the use of a longer radiator and double-matching tuning with linear phasing techniques that provide low SWR and more radiated energy. The double-matching also provides a DC path to ground to drain off precipitation static, giving an extremely low noise antenna capable of high power. SPT-500 is specifically designed to accept AM-FM-SSB-DSB signals with low loss. Handles 1.5 killowatts. This antenna is illegal for 11 Meters use.\n\u003ctable border=\"1\" cellspacing=\"0\" cellpadding=\"2\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth colspan=\"2\"\u003eSPT-500 Antenna Specifications\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGain (dB)\u003c\/td\u003e\n\u003ctd\u003e5.3 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSWR (at resonance)\u003c\/td\u003e\n\u003ctd\u003eLess than 1.2:1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal input impedance\u003c\/td\u003e\n\u003ctd\u003e52 Ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLightning Protection\u003c\/td\u003e\n\u003ctd\u003eDC Ground\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003eTwenty-two feet, six inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRadial Length\u003c\/td\u003e\n\u003ctd\u003eEight feet nine inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWind (Survival)\u003c\/td\u003e\n\u003ctd\u003e80 MPH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccepted mast size\u003c\/td\u003e\n\u003ctd\u003e1 ¼” to 1 ⅝” OD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eVideos\u003c\/h3\u003e\n\u003ciframe width=\"941\" height=\"539\" src=\"https:\/\/www.youtube.com\/embed\/YJvxpAKPbik\" frameborder=\"0\" allow=\"accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\n\u003ch3\u003eProduct Manuals\u003c\/h3\u003e\n\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0289\/7782\/3843\/files\/SPT-500_3dfce983-478f-4960-bfd0-da6e803c5685.pdf?v=1608220157\"\u003e\u003cb\u003eDownload Product Manual\u003c\/b\u003e\u003c\/a\u003e","brand":"Hy-gain","offers":[{"title":"Default Title","offer_id":43270031212607,"sku":null,"price":259.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/1233\/9519\/files\/SPT-500.jpg?v=1779144776","url":"https:\/\/hy-gain.com\/products\/spt-500","provider":"hy-gain","version":"1.0","type":"link"}
