Review on Walkie Talkie Antenna NA-320A Triband HT Antenna 144-220-440Mhz Antenna SMA-F Compatie With Baofeng UV-5X3 UV-25X4 UV-82X3 BF-R3 UV-9S UV-5R MK3X Two-Way Radio (2 Pack) By LUITON by Mike Devine

This is the only tri-band antenna that actually operates at 220MHz. All others were dual-band antennas with SWR > 50:1 at 220 MHz. This antenna has very good matching at 220 MHz (1.32:1) and at 440 MHz (approx. 2:1). It resonates on 3 bands, but unfortunately the SWR on 2m is 4.5:1. The lowest SWR on VHF was 2.35:1 at 116MHz. The base is quite wide and may not fully engage your radio. I tried it on the Baofeng UV5R and it barely turned on, but on the Pofung and Tidradio radios the antenna doesn't screw in far enough to make contact. The antenna of the Tidradio TD-F6 is not screwed in at all; it falls within the frame of the LED (see photo).
