This thing is perfect for my XG-100P. I keep the radio in my backpack, relocate the antenna to the top center of the pack, and clip the speaker mic to my jacket. Then I put the acoustic tube earpiece in and go for a hike. I can monitor for emergencies and talk to hams with no wires between the pack and mic. I can’t even tell I have a heavy XG-100P with me. When I’m at home, I can set the radio in an ideal location and sit on the couch and there’s no chance I’ll pull the radio off the counter when I grab the mic.
Love it!!
