ok, in my case, all of my HT's have the BNC adapter on them, so around the house, "where our repeater is located" I use Low power and a Nagoya Nub "BNC" antenna, combined smaller than original antenna, and more gain, and allows me to swap out to a piece of LMR400 coming from a UHF antenna on my tower for Dx'ing. and still allow for quick deployment when I get in my truck. It's a convenience thing. It may not be a "thing" for you or your application. did my best explaining. since I could not seem to up load pic's.
