I have had this antenna for about a week and did some SWR testing on it while connected to a Baofeng BF-F8HP 8 watt radio. I just threw the antenna on top of my Tacoma and did the test in less than ideal conditions, in a suburban neighborhood with lots of clutter around. As you can see from the photo it didn't love the bottom of the 70cm UHF band but even at the worst, it was at 1.7. Most of the readings were well below 1.5 and that is considered by most to be an excellent reading. The magnetic base has not budged even up to 70mph and I accidentally backed into my garage without unscrewing it, no damage resulted surprisingly.
Long enough cable, split connectors, reasonable storing magnet (could be a touch stronger) but at least it does not hurt the paint. Unable to provide Technical performance details other than it allowed me
To make contacts at reasonable far distances using a Baofung 5v
First, the PL-259 connector on the antenna coax would not seat into the PL-259 Female on the SMA adapter. Whoever soldered the connection got a little messy. It took a #20 drill bit to clean the female end. A little bit of emery cloth on the male end and all was better. Out of the box 2M SWR was 1:3. 70CM SWR was 1.4:1. Magnet is strong but not so strong you're fearful of scratching the paint when you remove the antenna. Durability lost a star because the SMA adapter seems somewhat fragile. I will tweak the SWR this weekend. I would recommend this antenna to a friend. Nothing has changed as of 9/21/2018.
I really like this antenna as it is sturdy and fits perfectly on my pofung BAOFENG BF-F8HP handheld receiver transmitter (HT). The magnetic mount is strong so I won't have to worry about it blowing off of my car while I'm doing 60 MPH down the road. The build quality is really good too with plenty of extra feed line too!!! I'm so glad I made this purchase.
Once I get into a hobby, I tend to go "all in" over time. What started as a vague interest in FRS/GMRS walkie talkies turned into the purchase of multiple BaoFeng VHF/UHF handheld two-way radios and a BTECH AMP-U25 mobile amplifier. Initially, I had a Nagoya UT-308UV magnetic mount car antenna which worked fairly well when connected directly to a BaoFeng BF-F8HP two-way radio, but upgraded to this UT-72 Super Loading Coil 19-Inch Magnetic Mount VHF/UHF Antenna with a PL-259 male connector to mate with the AMP-U25's SO-239 female connector. The upgrade was amazing!
The difference in quality, power handling, and most importantly SWR, was night and day. The UT308UV measured over 2.5 SWR, allowing just under 15W of RF power to leave the transmitter. The UT-72 super loading coil antenna reduced the measured SWR to 1.2, delivering almost 20W of power. This is a remarkable improvement, not only in power delivery, but in safety to the UHF amplifier.
The Nagoya UT-72 Super Loading Coil 19-Inch antenna is arguably the best magnetic mount mobile antenna for VHF/UHF applications. Highly recommended.

The cable is long enough to go all the way across my mini van from the rear all the way to the front. The material is very durable and when I'm on the autostrada I can go 90 miles an hour and it doesn't move. The reception is absolutely perfectly clear. It took me less than 5 minutes to install I'm so happy with this product I can't even believe.
Nice antenna, I bought 2. One for mobile and one for indoors inside my apartment. I bought a TRAM 1465 Land Mobile Base Ground Plane Kit to go along with the indoor installation. Although they recommend the Nagoya RB-50 (5" Base) 5/8 NMO Mount Magnet, 18' RG-58 PL-259, Includes Rain Cap magnet mount, I wouldn't do it. This antenna needs a ground plane and a good ground. Magnet mounts just don't provide that. You'll notice a lot better receive and transmit signals with a good ground plane. I bought the New Tram Browning Black 1246-B Trunk Antenna Mount NMO With PL-259 connector and 17Ft of RG-58 Coax Cable This antenna comes with an NMO to SO-239 adapter already, so you don't need to buy one.
This antenna is exactly what the GMRS market needed. The problem with most GMRS and FRS radios is that they have an antenna permanently fixed to the transceiver, and this costs big time signal losses since if you transmit in a vehicle, lots of signal is absorbed by the vehicle. The Nagoya antenna allows 100% of the signal to be radiated in the clear - other than minor cable losses. Much improved reception. With a couple of these antennas and line of sight conditions you can easily make 60 - 70 miles. Another important thing - the magnet on the antenna base is powerful enough to stay put on a vehicle roof at any speed. And it's covered by a rubber pad, so no roof damage.
MY 10-in-1 NAGOYA ANTENNA REVIEW AS SEEN ON THE ATTACHED PICTURES FROM SMALL TO LARGE:
- #1: NA-810 2.5-Inch Mini: Great when you know you only need short distance communication with low power and don't want to attach a longer antenna. This one has enough flexibility and very short, so definitely works as a pocket solution. Reception and Transmission were both the SAME as with the stock antenna, so it IS a good option to replace the rigid and long stock one.
- #2-3: Nagoya NA-701 and NA-717: Both have the SAME performance, so the selection should be based on one's need. If someone is an "action" type of operator who works in an environment where the radio gets bumped all over, then the ultra-flexible NA-717 is the option. Otherwise I would recommend the NA-701, which has stronger built and therefore better durability.
- #4-5: Nagoya NA-771 and NA-771R. The 771 has a bit of better performance, but due to its size, it can be a REAL hassle to carry it around, while the 771R Retractable version can be collapsed into tiny size to be carried easily, HOWEVER, such as the case with ALL such antennas, it is VERY fragile, MUST be expanded and collapsed with GREAT care, and has ZERO flexibility, so it is NOT suitable for active outdoor "action", for which the long and flexible 771 is the solution. But, if someone uses the 771R as a stationary transmitter unit without moving much about, then it IS a VERY good antenna!
- #6: Nagoya NA-24J: It is basically the super-lightweight ultra-flexible version of the 771, which is made for more tolerance for wilder "action", and also, due to its very-very light weight, it will NOT put so much stress on the antenna connector when gets jerked around. Not absolutely necessary to replace the 771, but definitely a good upgrade.
- #7: Nagoya NA-702DV: This antenna was made for the Baofeng UV-82X model that operates on the 2m/1.25m bands (144/222Mhz), which came out with the rigid low-performance stock antenna that I immediately upgraded to this one with much improved performance in addition to flexibility! So it's definitely a good upgrade with tolerable size that I can definitely recommend for that radio, or any other dual-band 2m/1.25m unit.
- #8: Nagoya NA-320A: A "MUST HAVE" for any VHF/222/UHF Tri-Band radio, such as the BTECH UV-5X3. The only drawback is the size of this otherwise VERY GOOD antenna, which can be a REAL hassle to carry around in any event, outdoor or indoor, BUT again, it solves the antenna-swap problem when switching from UHF/VHF to the 1.25m 222Mhz band. So something for something.
- #9: Nagoya UT-308UV: Very good magnet-mount antenna with immediately recognizable performance increase compared to any of the handheld antennas. But again, this antenna MUST be mounted on a flat metallic surface, the bigger the better, in order to make it work! NOTE: Since my review the UT-72 came out, which is an improved version of this antenna, so it is recommended to pick THAT model over this one, but it is an excellent antenna for me, I still have ZERO complaints on either transmit or receive.
- #10: TB-320A Fold-Over 39-Inch PL-259 Mount Tri-band 2m/1.25m/70cm (144/220/440 MHz) Antenna: I've purchased this very long antenna in order to upgrade my UT-308UV (which by the way is an excellent one), so I could utilize the Tri-Band feature, and perhaps get a bit more range as well. Since I use it as a base-antenna just placed outside the window on top of the Air Conditioner, the ground-plane is not idealistic, but still, it seems to work perfectly! My reception improved a bit but nothing drastic. The antenna is mounted on the RB-50 base (sold separately) which has a big and strong magnet. The "fold-over" feature is very useful for people who use this antenna on top of their vehicle when they want to park. One thing I'm not sure of is just how well would this configuration stay on top of a car when driving in higher speeds. Though the antenna itself has enough flexibility, I'm not convinced it could stand the abuse long term in everyday use, and since the top part is held in place by a tiny single little screw, in my opinion, there is a good chance it could get loose due to vibration. The cable is plenty long, so organizing it in a home or a large vehicle is also possible. Overall it is a rather expensive upgrade, but since it can take up to 200W power on VHF/UHF and up to 100W on the 1.25M band (the "quiet-band", which is my personal favorite), it surely can perform both as a mobile or base station antenna. And for that, I find that the price is still acceptable for a tri-band antenna.
SUMMARY: Well, everyone should pick the PROPER antenna for the application and circumstances they need, but for one, I can testify that ALL of my Nagoya antennas easily outperformed ALL of the stock antennas that came with my radios, which includes even the ones that came with multiple GOOD antennas and even long high-gain antennas, so I would still recommend an upgrade, especially for low-end radios that come with rigid, low-performance that strongly degrade the radio's optimal performance. For me, the difference was immediate and drastic, that is why I've got all these antennas from this brand.
IN THE PICTURES: My antenna line-up and a couple of radios with the antennas attached for samples.
Finding 3 band antennas is difficult. I was happy to find this one at a good price. I installed a new radio and put my sir member in line. I used the NMO mount existing on my car. Fit perfectly. SWR 1.0:1 on 220. 1.02:1 on 2meters. About 1:4:1 on 440! I love it.
