By adding selectivity ahead of your scanner or wideband receiver's front end, it reduces strong out-of-band signals that would otherwise overload the first mixer stage — resulting in less interference and noticeably cleaner airband reception. Compatible with virtually any scanner or wideband receiver on the market, and suitable for use with both external antennas and directly under the whip aerial of a handheld receiver.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBandpass filter optimised for VHF airband: 108–136 MHz\u003c\/li\u003e\n\u003cli\u003eReduces strong out-of-band signals that cause receiver overload and intermodulation\u003c\/li\u003e\n\u003cli\u003eLow in-band insertion loss: approx. 4 dB (VSWR 2:1)\u003c\/li\u003e\n\u003cli\u003eBNC female socket (antenna input) and BNC male plug (receiver output) — inline connection\u003c\/li\u003e\n\u003cli\u003eCompatible with all scanners and wideband receivers regardless of brand\u003c\/li\u003e\n\u003cli\u003eSuitable for external antennas and handheld receiver whip connections\u003c\/li\u003e\n\u003cli\u003ePassive design — no power required, no signal amplification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFilter type: Receive bandpass\u003c\/li\u003e\n\u003cli\u003ePassband: 108–136 MHz (VHF airband)\u003c\/li\u003e\n\u003cli\u003eIn-band insertion loss: ~4 dB\u003c\/li\u003e\n\u003cli\u003eIn-band VSWR: 2:1\u003c\/li\u003e\n\u003cli\u003eConnectors: BNC female (input) \/ BNC male (output)\u003c\/li\u003e\n\u003cli\u003ePower: Passive — none required\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Remove the ABF128 from the antenna input when monitoring frequencies outside the VHF airband, as signal strength on other bands will be significantly reduced.\u003c\/p\u003e","brand":"AOR","offers":[{"title":"Default Title","offer_id":57537053294936,"sku":"MOON-97-829","price":49.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/8753\/5192\/files\/97-829-3.jpg?v=1781869584","url":"https:\/\/kamsat.co.uk\/products\/aor-abf128-vhf-airband-bandpass-filter","provider":"Kamsat","version":"1.0","type":"link"}
