GHS 20/GWS 20 Wireless Remote Hub & VHF Handset - Black: The GHS 20 is a wireless remote handset allowing full control of your VHF 200, 300 or 300 AIS series* radio from a remote location. The simple design offers a backlit LCD display, soft keys and a rotary knob to adjust volume, squelch and channel selection. A 16/9 softkey automates distress calling while a large rechargeable lithium-ion battery provides a quicker charge and longer range. For full wireless capability, a GWH 20 wireless hub is required (the radio only supports 1 GWH 20). We offer a bundled version of the GHS 20 with the GWH 20. The GWH 20 provides intercom capability with the base station and supports up to 3 GHS 20 handsets onboard. *A software update may be required before you can use the GHS 20 with your VHF radio.
