I admit to a bit of skepticism that this antenna would make that much of a difference, BUT IT DOES. I'm now able to hit several 2m repeaters that were out of range using another antenna without ground planes. It works pretty well on UHF, and I've been able to receive NOAA weather radio stations up to 60 miles away. It's an impressive little piece of equipment.

I was looking for a quick cheap temporary 2 meter antenna. Wow. This thing is really well built ans the base radials really make a tremendous difference as I do not always have it on a metal surface which otherwise would provide a good ground plane. So I have it on a book shelf indoors and it works amazingly well due to the three base radials. Quality is jolly good and I have no complaints. The cable quality is fine and the PL259 connector is of quality. This was supposed to be a temporary solution, but it is now going to serve long term. My recommendation speaking as a ham who has been doing this since Marconi's days...just buy it. You'll be happy and amazed. Five stars !

Receive side, is fair with ground plane on, poor with it off.Transmit side, is basically like talking on a HT/handheld, no matter if ground plane is on or off.Very cheaply made.Will not buy again and would not recommend.

No signals...Unless you include the weather Chanel. Epic Fail.

This antenna is awsome. I'm getting 1.00 and 1.01 on the SWR meter in FRS/GMRS low and high power.Great value for the money.

Rx and Tx is better than any HT antenna. Main whip is easily tunable with a turn screw and included hex tool. You can also trim the 3 short ground plane rods to whatever frequency you want to transmit on mostly or just not install the ground plane part at all if you don't need it, (if it is stuck to your metal car, that is the ground plane so no need for the 3 extra bits). The 3 little antennas attach to a modular part so it can be removed completely if not needed. Magnet is strong. It is much more sturdy and metal than those little garbage ones with the twist in them that break in a week. It comes with adapters for your baofeng or tidradio. You can even skip the mag mount and plug it right in to your HT for even better Rx and Tx (This is where you want the 3 little antennas as there is no ground plane if you plug it straight in to the HT with no mount or cable). The coax is also nice and thick and won't break when I shut my car door on it (I might still cover it with a little tape for friction reasons). Pretty decent materials and construction actually for the price. I may recommend taking the rubber bottom off and filling the inside with hot glue or something just to seal everything and secure connections. It hits repeaters in a very busy area with 1.5 watts from at least 10 miles when mounted on a car when you have it tuned. I feel like it could do 40 or 50 miles to a repeater no problem from a hill with a "10 watt" HT.

See review photos. UHF Amateur radio band of 430 - 450 MHZ has SWR of 1.04 - 1.24 or so - Very good! However this listing says the antenna is dual band. On the VHF Amateur radio band of 144 - 148 MHZ the SWR is 4.86 - 5.05 (so bad, it may harm your radio to transmit at full power). I tested twice with the long and short ground radials with similar numbers for the sake of an Amazon review +/- 0.2 SWR. Note I'm only testing the amateur radio bands - all the way up at 174 MHZ this antenna is pretty decent with 1.35 SWR and it will be much worse than 5:1 lower than 144 MHZ. It is advertised as 136-174 + 400-470 which appears to be a wild exaggeration for appropriate use. If you only need UHF, this antenna may be ok for you. However, I will be returning it - the SWR on VHF is so bad it would probably harm my radio to transmit at full power. I will leave 2 stars for the UHF portion of the antenna being useable for amateur radio but had to take off at least 50% for the VHF being unuseable and a little more for the exaggerated service range. All tests done with a NanoVNA H-4 freshly calibrated.

When I saw this on Amazon I laughed. Now I'm the joke.What a nice, well-engineered, well-made mobile ground plane antenna.I only use it on VHF currently.1. The SWR is QUITE low at 25 watts from 144 Mhz to 158.00 Mhz: 1.1 to 1 and at its highest point 1.3 to 1 at 158 Mhz.2. Just after installing it Iowa suffered a snowstorm, then an Ice storm, then thunderstorms with really high winds, 50 mph+. This thing held on like a champ.3. I hit and made contacts on repeaters more than 60 miles away at 20 watts. The truth is I get about 17 watts total on High power with my radio so this antenna is doing most of the work.4. I never bothered to tune the antenna. I simply put it on my crummy Equinox.5. The PL 259 end is a little cheap, but I have buckets of those standing by as well as a soldering gun.6. Last night the band opened because of the unusually warm weather and I was making contacts 500 miles away on Simplex. From Iowa, I spoke with stations in Minnesota, Wisconsin, Michigan, Indiana, and Ohio. Again the antenna did most of the work.The design allows for its own ground plane, thereby being tremendously efficient. This allows the radiator or verticle to provide greater gain. It is center-loaded, and I hit several garage ceilings without trouble. The radiator is a vinyl whip with lots of give and tolerance.I am buying another before all of you other mugs figure this out and make it scarce.

At first this antenna seemed quite nice. I put the longer radials on it and used it indoors for 2m 440 hand held and a 2m mobile rig. Swr lower on 440, but approaching 3 in the 2m band but whip doesn’t have the extra length to adjust to lower the resonant frequency. So it’s useable, but not great.HOWEVER, after using it a while, I started to notice that it was a bit loose where the antenna part screws to the base. Then I noticed my receive strength on local repeater was low, and Swr jumped way up. Thank goodness I had the Swr meter in line! I had to rip the felt off the bottom to access 5he wires inside, and found that the looseness of the connector had allowed it to rotate slightly, and that actually broke off the center conductor. In repairing it, I found the center conductor is not copper but rather copper plated steel. Also, the braid was soldered to the threaded area of the connector as opposed to a lug, so a large soldering iron is needed to reflow solder there when repairing. There is no lock washer to hold the nut tight, so the only thing that keeps it from coming undone is the oversized D shaped hole that the connector mounts in. Well if that nut isn’t tightened really tight, the connector can rotate back and forth and break the center conductor. I used some red thread lock and a socket to really tighten it up, and soldered it back together. Gotta put some hot glue in there around the cable to duplicate the factory strain relief. Don’t have the nice felt bottom any more. I do see now that I could have just cut the center part inside the magnet out for a neater repair.So in short, seems like a good antenna, though not tunable for low Swr. Made with cheap cable and prone to breakage. Once that center conductor is detached, radio is transmitting with no antenna. Not sure how fast you need to notice this before radio finals burn out…

This thing is awesome. Didn't think it would work even close to as good as it did. Put it on my truck and a massive improvement over the antenna I was using before. Might have to buy another one for our other vehicle.
