I've had a Unication G5 for a little over 24 hours. So far, I'm very impressed with the reception, especially compared to scanners that don't seem to work well in my area.
Here's a video as an example of the G5 pulling in the Fort Worth Regional Radio System, layer 2/P25 simulcast. I had the scanners focused on Fort Worth Fire as well, and they just don't get it. Now, I could probably move the Uniden and the Whistler to certain spots and get ok reception, but with the G5, it's not necessary.

That's not to say the Unication G5 is for everyone, but it will certainly relieve some of the simulcast issues I have. It will be especially nice while driving or walking around, when it's not practical to hold your mouth just right, and point a yagi at some random direction, like I have to do with Uniden and Whistler scanners.
I purchased mine from
http://www.rayspagersales.com. He was the quickest to return calls and emails, and once I purchased he was quick to ship.
Happy Scanning!
