VHF/AM-FM/AIS splitter

TEST LAB TESTED_Tavola disegno 1logo


The RA201 splitter allows to use just one VHF antenna to simultaneously receive the AM/FM and AIS radio signals; furthermore, the VHF transceiver can also be used.

It is a compact, economical and safe element, easy to install in any place. It requires only a 12V power supply with maximum of just 25 mA power consuption.

It is provided with a coaxial input for the antenna and three outputs for VHF, AM/FM radio and AIS.

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 its three applications, ensuring effective transmission and reception for VHF.

The splitter maximum power for VHF is 100 W, therefore twice as much as most devices on the market.


  • Impedance : 50 Ohm
  • Range of radio reception : 100 KHz to 200 MHz (GO/PO/OC/FM included)
  • Range of transmission/reception VHF : 100 MHz to 200 MHz (marine/ham radio)
  • Range of AIS reception : 100 MHz to 200 MHz
  • Built-in preamplifier : 15 dB shared on two inputs (to compensate power loss)
  • VHF power range : from 0.2 watts min to 100 watts max
  • Maximum consumption : 25 mA
  • Voltage supply : 13.8 V (from 10 V min. to 16 V max)
  • Cable supply : length 60 cm (2 feet) red (+) and black (-)
  • Protection : glass fuse 5×20 mm -315 mA (included)


  • VHF antenna: : SO239 jack
  • VHF : RG 58 C/U cable 60 cm (2 feet) long + male PL259 plug
  • Radio : RG 59 A/U cable 60 cm (2 feet) long + male Motorola plug
  • AIS : RG 58 C/U cable 60 cm (2 feet) long + male BNC plug
  • Casing : length 83 mm (3” ¼) x width 48 mm (2”) x height 38 mm (3” ¼)
  • anti-spreading metal-epoxy paint, high resistance to rust and oxidization
  • Fixing : by 4 M4 crews

Connect the antenna cable with a PL259 connector to the splitter RA201 S0239 jack

Connect the marine VHF radio to RA201 using the marine “VHF radio” cable of RA201

Connect the AM/FM radio receiver to RA201 using the “AM/FM radio” cable of RA201

Connect the AIS receiver only to RA201 using the “AIS receiver” cable of RA201

Connect the splitter’s power supply (use a switch to cut the power)


  • Make sure that power supply polarities are not reversed: red to positive (+) and black to negative (-)
  • Do not use without first connecting the VHF antenna
  • Do not reverse the connections
