.Do these make a big difference? I was looking into using one with an HP-1. Wanted to get better signal strength for a local P25 system.
You're right warren, but our local's go digital less than a mile from the sys tower so I think it's more of a multi-path problem in this area.The difference they make depends on where you live. In a rural area they work as intended, in an urban environment saturated with RF the difference will be the law of unintended consequences, tons of interference. FYI, P25 is all or nothing so signal strength doesn't mean a thing, as long as you're hearing it that's all that matters.
