Glomex RA201 VHF/AIS/RADIO Active Splitter

Regular price $70.00

The Glomex RA201 splitter allows the use of just one VHF antenna to simultaneously receive VHF, AM/FM and AIS radio signals; without sacrificing performance on the VHF radio transceiver. This compact and economical splitter is compatible with all our AIS receivers.

The unit comes with a coaxial input from the VHF antenna and three outputs for VHF radio, AM/FM radio and AIS receiver. It requires only a 12Vdc power source with a maximum of just 25 mA power consumption.

Thanks to an electronic circuit specifically developed by Glomex and the presence of a built-in preamplifier, the RA201 splitter is able to offer high performance in all three applications, ensuring effective transmission and reception for VHF.

The splitter’s maximum input power for VHF is 100 watts, twice as much as most devices on the market.
