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

Great product

Good fit and performance
A few other bnc antenna were wobbly on my Whistler 1040 scanner. The fit was much more stable. Connected to my HT with sma adapter and the reception was slightly better than my other antennas of similar length.

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. I’ve used it for train channels and ATC for airports for drone flights. Price is reasonable.

Well worth the price!
I have a sds100 and for my area this antenna works great. I bought I remtronix 920s and 820s and they were double the price and I returned them. Note: Everything depends on your area what works for me might not work for you. I just felt I should give this a great review for the price, build and works great on simulcast and dmr.

Solid choice for your HT
Solid antenna that pairs nicely with my UV-PRO. It is long tho so keep that in mind depending on your intended uses. Great reception and no issues with signal reports while transmitting.
