Authentic Genuine Nagoya TB-320A Fold-Over 39-Inch PL-259 Mount Tri-Band 2m/1.25m/70cm (144/220/440 MHz) Antenna, includes NMO to UHF (SO-239) Adapter

This review is for the the Magnet Mount dual band version. Great little antennas. I specifically like them because of the wider base over say a Diamond. It's not going anywhere. I like the adapter for your HT as well though I am not too confident on them lasting. I have one on the car and one on top of a metal safe in my house. Both work great for local nets and simplex. Works good enough on GMRS too with a bit higher SWR but still in working range. If I was mainly using it for GMRS I would get the GMRS specific one they make though.

I bought one before and forgot to tighten the top part of it down and it fell off the truck so I ordered another one to replace it. It has a strong magnet and works really good with the radio

It is designed for both amateur radio and general communications use, featuring a strong build that can withstand outdoor conditions. With a 2m/70cm dual-band frequency range, it delivers good signal reception and transmission quality, making it a popular choice for mobile operations. The antenna is easy to install and offers a decent balance between performance and convenience, although it may not offer the same high-end performance as larger antennas. Overall, the Nagoya UT-72 is a reliable and affordable option for radio enthusiasts who need a portable antenna solution.

Worked well for me. Magnet is strong and I’m able to pick up all my local repeaters. For the price, can’t complain. Haven’t got around to checking SWR.

I own 3 of these. 2 mounted on vehicles, the 3rd is being used as a base station antenna.They are stellar performers.The 2 meter band and murs has a flat 1.0 swr.70 centimeter has an swr of 1.0. The gmrs has a maximum swr of 1.2.I am able to make solid uhf repeater hits up to 40 miles away.This is a quality dual-band mobile antenna.

Great range, much better than ecpected

I tested this antenna on a Nagoya mag mount in the center of my roof, with a Surecom SW-102, 6ft of LMR-400 and three radios. A BTech GMRS-20V2, Yaesu FTM-200DR and TYT MD UV390. On 2m @ high power the Yaesu avg 1.3 SWR @ 45W. On 70cm the Yaesu avg 1.5 SWR @ 35W. On GMRS @ high power the BTech avg 1.7 SWR @ 20W. On 2m @ high power the TYT avg 1.01 SWR @ 7W. On 70cm the TYT avg 1.3 SWR @ 7W.I have a better performing dual band antenna within 2m/70cm and a better GMRS antenna for single band use. But, for the low profile, across all 3 only the Nagoya UT-72 has performed better so far and not by much. The UT-72 gives up some DBi in 2m though. I was able to hit and hold several repeaters past 30mi @ 2m on the NMO 72 that I was not able to with the UT-72The reasons I wanted this antenna:1.) I pinched the cable on my UT-72 and the cable and mount are non standard so I can just swap mounts to keep using the antenna. I would have to buy the whole thing again. Why not try something new?2.) I don't want 2 antennae and I wanted more range at 2m.3.) I wanted the most performance with the lowest profile. My personal testing with the stubby stealth antenna was abysmal. The NMO 72 is a bit shorter than the UT-72. I can't really have a much longer antenna, nothing in the 30+ inch range for certain because of where I work.I keep couple larger antennae in the car in case I'm out and about and need them or if I am on a road trip. But for daily commute this antenna is ideal for my purposes. Until I find a better option this will be my primary.

UT-308 UV.Gain figures are misleading in the description. Stated plainly as "1.7 - 4.15", it should read "1.7(VHF) / 4.15(UHF)". I expected more gain on 2 meters than 1.7. My Nagoya 771 hits stronger. I'll keep it inside the car until I need it. Then it's a simple matter of opening the sun roof and reaching backward through it to mount it in the middle of the roof. Then I close the sun roof with about an inch of gap for a more solid ground plane.Build quality looks good, powder coating is smooth and flawless, and the SMA Female connector seems attached strongly to the cable. I have no use for the separate extension, but I'll toss it into my parts drawer. Haven't had a chance to test SWR or power out yet.I keep the antenna element inside a length of 7/16" PVC pipe with end caps to protect it. I also stuck a length of black reinforced vinyl electrical tape across/onto the bottom of the rubber cup insulator that surrounds the magnet ... with an inch tab of the tape projecting out from under the mount to aid in removing the antenna from the roof. Fold the projecting electrical tape back onto itself to form the tab. I don't like straining the mounting boss atop the mount to pry that magnet loose from the roof; as other reviews testify, it is very strong.For quick comms, I intend to use my Nagoya NA-771 mounted on my Baofeng BF F8HP Pro poking up all the way through the open sun roof before I go through the bother of setting this one up on the roof. For more involved comms and to avoid my arm getting tired, this UT-308UV will fit the bill, I think, notwithstanding the low 2 meter gain figure.
