Antenna fits handheld Icom IC-M31 marine radio. Also fits IC-M21 IC-M23 IC-M33 IC-M35 IC-M3 EURO This is an unbranded unit but works perfectly on my radios. Appearance is identical to my original. I have some spares because it was cheaper to order multiple units. They can be tricky to get hold of as the M31 radio is now discontinued. The antenna can become brittle and fracture which is what happened to mine so I now carry a spare.
