​Great product, works as advertised

Noticed the difference with this one. But pricey

After a pretty lengthy evaluation under varying signal strength, I found it to be a good performer, but not that much better than the stock antenna on the SDS100.

This Scanner antenna is very nice. It helped to receive a lot more channels and it is flexible so if I bend it, it doesn't break. Highly recommended.

Bought the 820S for my new SDS100 because I wasn't getting the reception I wanted in the "hole" I live in. One of the main systems I wanted to pickup was a local 850-860 MHz P25 Trunk System that shouldn't of been a problem. With the OEM antenna, the scanner would not hold on to the control channel for very long. The signal strength bars at the top right were 1, maybe 2, at best, but a lot of the time it would drop down to no bars and it'd go searching again. I confirmed this bad signal strength by moving around my house until the signal improved and the radio traffic resumed. As soon as this antenna arrived, I swapped it out and the signal strength immediately shot up to 4 bars, the scanner held on to the control channel easily and the chatter began! Haven't had a problem receiving this system since. Also confirmed that the signal of lower frequency, conventional, systems received just fine as well. Very happy with this purchase! Thank you!

Though I didn't work up the numbers; this antenna is better than what came standard on the SDS100. Getting clear signals from over 20 miles away.

I don't know about the other reviews but this did nothing to help my scanner which I way overpaid for that scanner is no good either SDS 100
