Antenna combiner proFIL 4201

High power DSC / AIS TX duplex cavity antenna combiner for VHF antennas. High-performance proFIL™ technology combines separate VHF DSC (ch70 digital selective call) receiver antenna and AIS (automatic identification system) transceiver antenna into the same antenna without compromising safety and performance. By using a common VHF antenna for both AIS transceiver and DSC receiver, cabling is reduced and less space is occupied at ship’s topside. Installation of AIS equipment can be instantaneous. Compared to IMO recommendations, high isolation proFIL™ technology separates two radios virtually by over 200 meters instead of recommended 5 meters. Its low loss technology on all ports does not disturb the sensitivity of the communication equipment. enables fast installation of AIS equipment • works simultaneously with DSC reception and AIS transmission • high isolation • robust design • can be used with proISO 1001 to prevent ground loops
