I am selling on eBay a generic Seperation Kit similar to YSK-7100. It does not include a bracket however. This is a substitute to the Yaesu YSK-7100. This kit includes a 20' cable for the control head, a 20' microphone extension cable with coupler and a 12' speaker extension cable. Yaesu sells the entire separation kit for what many consider to be an outrageous price and this set of cables will do the exact same thing to allow you to remote mount the radio.
