The LM-1001 clamp mount has a 4 hole amps plate that can attachd to the remote head brackets from Icom for the ID-5100, IC-2730 or IC-2820 directly to this mount. It will also work with the remote head bracket that comes with the Kenwood TM-D710 or the TM-V71a if you have the optional remote head bracket DFK-3D. If you have a Yaesu remote kit you can attach the remote head bracket that comes with the bracket like the FT-7800, FT-7900, FT-8800, FT-8900, FT-857. This will work with the mobile remote head kits from Anytone, BaoFeng and Wouxon as well.
The 4 holes amps plate is the one you want to use with our EXT-01 Extension plate. The holes in the EXT-01 line up with the holes on the AMPS face plate.
