📻 Radioddity RD-301 Tri-Band Antenna: Optimal Range for Baofeng, BTECH, Kenwood Two Way Radios Review

Antenna arrived quickly. At the same time, according to my tests, 220 is not very good. I understand that a tri-band antenna is a compromise between bands, but I was expecting a bit more from this product as I've had better luck with other Radioddity products. Works just as well as any of the dual band antennas I have on the 2 meter and 440. I'm wondering if this is really a tri-band antenna. I have another tri-band antenna but it's huge and cumbersome to carry around. There are other antennas…

I can't say anything about the 220-225 MHz range as I don't use it much. But this antenna is the most reliable of several antennas I have for my Baofeng RT. I have a couple of Nagoyas that work pretty much the same, but this one is more reliable and has better reception. I would put this antenna first and then my TIDRADIO NA-771. I had to make a small rubber sink/faucet washer to fit flush with my baofeng, which is annoying when changing comparison antennas. However, this does not affect the…

I got terrible SWR measurements for this antenna when I connected it to my antenna analyzer. Then I did a little research. It turns out that the H/T radio is an important part of the antenna. The SWR is measured high without the radio when the radio is plugged in because that's not how it works. If you take an RF meter and measure the radiated power when the antenna is connected to the radio, you will find that almost all of the power is radiated. No energy is sent back to the radio. I also…

Surprised by good reviews. This antenna performed worse than the 220MHz antenna that came with the BTECH UV-5X3. There were a few 220 repeaters that I couldn't use with this antenna that could be used with a standard 220 antenna. Another interesting thing is that most of my portable radios generate RFI on my computer's speakers. The UV-5X3 does not generate RF interference with this antenna, but with a standard antenna. I know it's not very scientific, but it seems to me that the RF power is…

This is the shorter of the two tri-band antennas available for the BTech UV-5x3. In fact, this is the same design as the Nagoya NA/320A but half the length (and accordingly half the length of the Nagoya). 5x3 is much easier to handle. Of course, a half-wave antenna will outperform a quarter-wave antenna, but the bottom line is that this is a compromise in favor of ease of use, and the difference in performance is functionally less important when you buy this antenna. The 17-inch (half-wave)…

UPDATE: Radioddity customer service was very nice and gave me a replacement but had the same issue. HOWEVER, they also let me try the RD-371 (a longer tri-band antenna) and that seems to work pretty well. If you're having trouble with the RD-301, try the RD-371! I bought it to work with a Baofeng UV-5RX3 tri-band radio. The radio comes with 2 antennas, each of which is dual band. Not wanting to switch antennas, I decided this article would be my solution. My radio is even listed as particularly

I'm a first class operator and have the right equipment to measure these antennas both on suitable ground and in high temperatures. Below are the test results of the Radioddity RD-301 144/222/440 tri-band antenna versus the Diamond SRJ773A 144/440 reference antenna. Both antennas were under the same conditions during the test. For example. Same ground plane, coax cables, test equipment, location to objects, etc. The results are as follows: Antenna Radiooddity RD-301 Triband 144/222/440Fq…
