2 Pack ABBREE 42.5-Inch Length SMA-Female Dual Band 144/430Mhz Foldable CS Tactical Antenna for GMRS Radio Baofeng UV-5R BF-F8HP Pro 5RM UV-21R UV-5G Plus GM-5RH K5PLUS AR-152 GM-15PRO Radio Antenna

I use these with uv25X4 and they are dinomite I can hit repeaters at 2 miles, 18 miles, 25 miles away no problem. I can talk radio to radio at 18 miles with a uv82hp handheld nobody would believe it thought I was using a big radio. I have 3 on my go bag one on a packet radio other 2 one on qyt 8600 other on a tyt9800All of them work great. No problem with any of them. I like the quality they are a good buy. I have one of the btech copies and it works as good as the real thing. The 18 inch baofeng model is good but not as good as the longer one. They are almost as good folded as they are full length. 73s allKK70AV

I have not done any scientific tests but these antennas do seem to improve range and transmission clarity on GMRS. I can say with certainty that these are an improvement over the antennas that come stock with the Baofeng UV-5R gmrs.The antenna works while folded or unfolded. I do notice an improvement in range when the antenna is fully unfolded.The biggest advantage I have found to these antennas is that I can stick the radio in my car door cup holder and extend the antenna out of the window and I get far better range than with my antenna inside of the vehicle. The flexibility of this antenna is the only thing that makes this possible.Overall I am happy with my purchase and I ended up purchasing a set of these for two other people in my family who also use GMRS.I have folded and unfolded this antenna hundreds of times at this point and stuck it out of a car window and the antenna has suffered no damage or noticeable wear.For the price these are seem to be a great value and if you are having trouble with range in your area are worth a try.

The base on this antenna is very wide and the SMA fitting does not extend very far past the base. Which makes absolute sense because it's such a massively long and heavy antenna. However, if the antenna mount on your radio is narrow or deeply recessed, it will not work on your radio. It works on a few of my radios. It fits the AnyTone AT-D878 just fine, and the added length does increase the gain better than a simple rubber duck. It also fits Baofeng UV-5R's which is probably the radio it's more designed for. However, it does not fit a BTECH UV-PRO. Which was, unfortunately, the radio I bought it for. Owell, it still works fine on the radios it fits.

I just made contact through the ISS space station repeater with one of these attenna, and a 5 watt TD-H3 handheld. No yagi required. I was just playing with it for the first time, when I got an alert the ISS was passing by. So I folded it out completly, and thought I would give it a try. It worked. What is that like 250 miles and change? I was highly sceptical of these type of attenna. Now I am just blown away. FYI, the base seperates and seems to make a fairly usable stubby, for when you dont need the full attenna.

So nice to have.

While this antenna is not great to leave on your radio, it's easy to change, and with my factory antenna, I could not reach a repeater 70 miles away. However, with this antannai, I was clear!

Fits my Baofeng UVR5 perfect and increases the range . Great price too

I purchased these antenna at the recommendation of friends who have and use them on their Baofeng UV5R radios. They are very happy with the performance signal and range reception. The 4 star rating is only because I have not been able to use and therefore rate the antenna's performance myself. They were well packaged for shipping and arrived undamaged. I think the price is very reasonable, I mean a pair of antenna for $19, now that's affordable. One thing I really like is the ability to fold the antenna in half, thirds or fourths, with the latter making them easier to store when not in use. The antenna fit my Baofeng UV5R 8W radios perfectly with the use of the provided rubber washer between the antenna base and radio. How well the antenna hold up to constant folding and unfolding is another issue that only some time will tell, but considering the antenna is made of measuring tape, and I've some measuring tapes that are decades old, I expect they will hold up well for a long time. I will try to update my rating after a few months of use and add some photos or videos.
