Radioddity RD-371 Tri-Band Antenna 15.5in 144-220-440Mhz 2.0dbi SMA-Female Triband HT Antenna 2M-1.25M-70CM for Baofeng RD-5R, UV-5R/5RTP, UV-5RX3, Kenwood, Wouxun Walkie Talkie Two Way Radios (Black)

works great

Antenna works as advertised. Extends the range of my BaoFeng radio

great reception and range when positioned in the right area. fit well without any mods to antenna or radio. looks great, super high quality from radiodity again!

I ran a performance evaluation on this antenna and compared it against a quarter wave reference antenna. This is a tri-band antenna that covers the 2 Meter, 1.25 Meter and 70cm Amateur bands. On 70cm this antenna shows about 2.1 dB gain over the quarter wave reference. The other two band were on par with their quarter wave reference antennas. A word of caution: If you are using any of the cheap Chinese radios such as the Baofeng, and the VHF output is not filtered, then this antenna present a very strong 2nd harmonic over the fundamental transmitted frequency.

Bought this for my Beofeng. Very well made. Works great.

I an extra class operator and have the proper equipment to measure such antennas on a proper ground plane and also under HT conditions as well. The following are my test results of the Radioddity RD-371 triband 144/222/440 antenna compared to my reference Diamond RH77CA 144/440 antenna. Both antennas were put under the same conditions during the testing. Eg. The same ground plane, coax, test equipment, location to objects, etc.Radioddity RD-371 triband 144/222/440 antennaFq.

You will destroy your radio in a very short time. The SWR is EXTREEMLY high. Advertising this antenna for Transmitting on the 1.25m band is FALCE ADVERTISING! Even as a dual band antenna this antennas SWR is poor on both the 2m and 70cm bands. The SWR needs to be under 1.5:1 for best performance even before field strength testing. I did not wish to burn my radios up so I did not even do a field strength test on it. I will be sending it beck for a refund. Buyer beware! Test your antenna or have someone who has the proper equipment test it out before you transmit on your radio. Beware of YOUTUBE videos that show some guy testing these antennas out and having good SWR results. Test them out yourself. I mostly buy these just so that I can test them out and review them. On RARE occasion I stumble across a good one and keep it. But a work of advice. Buy a Japan made antenna. The Chinese ones are garbage for the most part with few exceptions.

Working well with my Baofeng tri-bander. No issues.

The first thing I did was check these antennas on my antenna analyzer and VNA. They are very good quality for the price range. They cover the bands that they advertise very well with low SWR. And they are even broadband enough to go quite a bit outside the specified range with still acceptable SWR’s, and match. Finally, an affordable antenna that can compete with the industry standard Nagoya
