Big Upgrade Over Included Antenna
used with a Uniden Bearcat 125...works way better than the rubber ducky antenna the scanner comes with

Great option
Allows me to get a lot further from the tower and clear audio, itโs very long so be mindful of that but the value is there 10/10 functions perfectly and as intended

Great product
Performed noticeably better that the stock antenna that was provided with my Uniden Bearcat handheld scanner.

Good upgrade from a stock antenna
Fits perfectly on my Bearcat 125 scanner. The range and audio quality is much improved from the stock antenna. Iโve used it for train channels and ATC for airports for drone flights. Price is reasonable.
