Antenna combiner proFIL 4120

Diplex VHF and UHF antenna combiner for wideband 30 - 512 MHz tactical antennas. Operates in ranges 30-80 MHz/ 108-400 MHz. proFIL 4120 and proFIL 4211 are designed to be used with tactical wideband antennas ranging from 30MHz up to 512MHz. Their low loss design enables the use of high power transmitters simultaneously. proISO 1150 combined galvanic isolator and lightning protector protects communication system from lightning strikes, EMPs, interference and static discharges. It also protects vessel’s metal hull from corrosion caused by DC-ground leaks. Combining several transmitters and receivers to single antennas by using advanced proFIL™ technology creates nstant advantages. Risks that are avoided immediately are: • reduced co-site interference • reduced intermodulation • saved space • reduced overhearing
