THE LEADER IN AMPLIFIER KEYING CABLES AND INTERFACES

We use a high quality 13 pin DIN connector and a high braid content cable with RCA plug for excellent shielding! 
The keying cable plugs into your radio 13 pin jack, and then to the RBI-1 buffered protective keying interface. The output of the RBI-1 has an RCA jack that provide a closure of contacts to activate amplifiers that require a ground or closure of contacts to activate.
Included: 
13 pin ICOM din keying cable 
RBI-1
RCA-RCA cable

NOTICE: The ICOM IC-7300, IC-7200, IC-7000, IC-7100, IC-718, IC-706, IC-706 series,IC-706MKII, IC-706MKIIG is only rated to switch up to a small voltage and current, so our RBI-1 interface included in this listing will protect your radios delicate amplifier keying circuit from voltage and current coming from your high power amplifier T/R relay

When connecting your Radio and Amplifier, there may be switching voltage, polarity, and current incompatibility  that can cause damage to your radio or amplifier if connected without a switching interface between them. Even if your internal radio switching looks like it might be usable, it is wise to have an extra degree of isolation between your amplifier and radio with our relay buffer interface.
