How can I ensure that I am buying the second generation of the sr-A10 antenna? Shawn March 06, 2019 19:36 If your antenna lights up blue, you have the 2nd generation of SR-A10 or SR-A10MM antennas. Related articles Would the SR-2K antenna or the SR-A10 antenna be a better match for the Stryker 955 and why? What antenna cable should I use and how many ohms ? Are you going to make a Base Radio? ARE YOUR SR-A10 AND SR-2K ANTENNAS MOUNTED THRU THE ROOF? I'm going to be buying one of your radios. I have a Willson 2000, should I keep my Willson or get a Stryker antenna Comments 0 comments Article is closed for comments.
