{"product_id":"av-525-ci-157p","title":"RAMI AV-525 VOR\/LOC\/GS Antenna","description":"\u003cp\u003eRAMI AV-525 is a receive-only VOR\/LOC\/GS V dipole antenna for 108–118 MHz and 328–336 MHz with an internal balun transformer and a female BNC connector. RAMI lists it as a direct replacement for the Comant CI 157P. The antenna is similar in style to the RAMI AV-12, spans 29.64 in (753 mm) and weighs 0.50 lb (227 g).\u003c\/p\u003e\u003cp\u003eIt has 50 Ω nominal impedance, horizontal polarization and an omnidirectional pattern; VSWR is 3.0:1 maximum in the VOR\/LOC band and 2.0:1 maximum in the glideslope band. Because the balun is built in, the receiver or antenna coupler connects through a coaxial cable with a BNC plug, such as Amphenol Connex 112116. The FAA has authorized the AV-525 to TSO-C34e, TSO-C36e and TSO-C40c; environmental qualification is to RTCA DO-160G. The antenna is rated to 350 mph and 50,000 ft.\u003c\/p\u003e\u003cp\u003eRAMI names the top of the vertical stabilizer as the ideal location, clear of reflections and shadowing from the metal structure. The antenna mounts through two 13\/64 in (5.2 mm) holes. Installation in a certified aircraft needs an approved modification and a Certificate of Release to Service. Fit depends on the aircraft type and the NAV receiver model.\u003c\/p\u003e","brand":"RAMI","offers":[{"title":"Default Title","offer_id":58184308293963,"sku":"AV-525","price":7887.9,"currency_code":"CZK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1055\/1063\/3803\/files\/AV-525.jpg?v=1790589615","url":"https:\/\/shop.airteam.eu\/products\/av-525-ci-157p","provider":"AIR TEAM","version":"1.0","type":"link"}
