Review on 🔁 Bingfu UHF 400-470MHz Two Way Radio Antenna Replacement Walkie Talkie SMA Female Short Antenna 2-Pack for BaoFeng BF-888S, Arcshell AR-5 AR-6 AR-7, Retevis H-777 H-777S, Kenwood FRS Radio by Lance Harrison

Don't expect this antenna to go far and don't expect it to work on VHF. I installed these antennas on two different analyzers (RigExpert AA-600 and nanoVNA). Both SWR at 2 m > 20 or more. At UHF, the SWR is about 1.3 at about 440MHz and about 1.8 at about 460MHz. I bought them for UHF so I don't mind that they aren't dual band but if you buy this antenna hoping to use it on VHF you will probably be disappointed. I bought these to mount a pair of UV-5Rs at 70cm for very close simplex communications. They work great for that. We're never more than half a mile apart, so it's fine.
