Review: Good upgrade for baofangs - Definitely a big boost in range compared to stock cheap baofang antennas Review: Works Well - Compared it to the AR-771 and the stock antenna on a retivis A3. The Diamond out performed them. Very happy with the Diamond 77CA antenna. The prefix determines the connection type. SRH is male, SRJ is female, RH is BNC.

My nagoya antennas dont work well with the BFF8** A: I'm using this Diamond on the BF-F8HP and it works great for transmitting, especially in more remote areas. As far as receiving, I havent really noticed much difference vs. the high-gain Baofeng antenna that it came with. In fact, I use the original Baofeng in the car because it receives better in the smaller space (less noise). **Q: will this work with teh Baofeng uv-9r?** A: Yes, since I believe that Baofeng uses a reverse SMA connector. The SRJ77CA will make a drastic difference on both transmit and receive; especially on weak, distant signals. **Q: I'm new with this stuff, do i need an adapter to use with my baofeng uv82?** A: I own the uv-5r and a f9v2+ and I can use this on both of them without and adapter the uv82 uses the same SMA antenna as those two so no you do not need an adapter. **Q: The antenna pictured if you click ad is not a Diamond (original) SRJ77CA. Not sure what the antenna pictured is. Can someone clarify before I order?** A: It is a diamond antenna. I've found it works better than the Nagoya on lower frequencies than the Nagoya... however the inverse is also true. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good upgrade for baofangs *by A***W on June 14, 2026* Definitely a big boost in range compared to stock cheap baofang antennas ### ⭐⭐⭐⭐⭐ Works Well *by B***B on May 18, 2026* Compared it to the AR-771 and the stock antenna on a retivis A3.
