Hi all, I am super green with antennas and I trying to get a 2m mobile setup in my '10 FJ Cruiser. I could use a little guidance with connectors/adapters. I have been following this particular setup, trying to get something similar going for my own ride: N4LS/M mobile ham radio installation (I will note that I am currently just planning to connect into an HT radio, as I am still looking for the right mobile station for the truck. So eventually will have a more substantial setup but is just going to connect to an HT at the moment) Right now I have the following items: Hamstick: ProComm PC144 - 2-Meter 144 MHz 3dB Gain Ham Stick Antenna 350-Watt Black Antenna mount w/ coax: K400S Trunk/Hatchback Mount The antenna mount is an SO-239 base and the hamstick is a 3/8-24 threaded connector. How the heck do I get those two connected together? My internet sleuthing and research has not been fruitful so far, as I guess I just don't have enough knowledge/experience yet. In the video, N4LS appears to have something substantial connecting the two, but not sure what it is (photo for reference): Not sure if this is better suited for the antenna forum, but thought I would try here first. Any help that can be provided is much appreciated!!
