It seems a little quiet, so I figured I would share a walk-thru video of a portable field setup for my radio gear. The video focuses on my Ham gear and two club events I am going to be involved in, but you can easily put something together like this for field use for any radio platform, including GMRS.
In fact, the X200 antenna works great for GMRS frequencies. I've posted the SWR readings from the analyzer in another thread, a month or so back. On the low side it was 1.3:1 and the high side was 1.4:1.
Not a pro video by any means, but you should get the idea.
