## Questions & Answers

**Q: Has anybody used this on the BF-F8HP? 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.

### ⭐⭐⭐⭐⭐ Works Well

### ⭐⭐⭐⭐⭐ Best antenna Ive ever owned.
*by S***T on October 5, 2025*

Best HT antenna out of all the different makes and models I own. Instant difference in clarity and reception the moment i put it on my handsets. I have several different HTs and its improved TX/RX on all of them, even the budget models work like more expensive HTs with this antenna fitted. As anyone who is into radios knows, its the antenna that makes the radio.
