Fit and finish: Excellent. It ships with the section above the center coil removed. A hex key is enclosed to tighten after inserting. You can't put it in too far, so there's no adjusting. It also comes with a chromed UHF to NMO adapter, also finished nicely. I don't believe other manufacturers include one of these, so if you were to buy a UHF-mount tribander from the "other" guys and decide to go with the tried-and-true Motorola mount, you can add about $10 to the cost. It also has a "fold-over" feature, where you pull up against some sort of internal spring and lay it over 90 degrees. It's a very strong spring, so it's not going to fold in a heavy wind or at higher speeds. For instance, Around here (Metro Phoenix AZ) if you're doing 80 on the freeways, everyone's passing you. I "kept up with traffic" for my hour or so commute and checked over the antenna afterward. No damage, no weakness, no nothing. In use: I compared this antenna to what I have, a couple dual-banders on my truck and a dual-band J-pole at home. I don't have fancy meters and such, but I can tell you the 320 compares very favorably to more expensive hardware. I had no problems hitting mountaintop repeaters on all 3 bands all over metro Phoenix. At the current price of $58 this item is $15 to $40 cheaper than the major players' equivalent antennas. For my money, it's well worth it Review: TB-320A Tri-band::Low/med SWR across all 3 bands. Good Quality. 1-antenna convenience - I was a little skeptical due to a previous review on this, saying that the SWR on the 1.25m / 222MHz, but I took a chance to test myself with my own simple SWR meter. After testing, I almost agreed with him, until I realized that my duplex shifting was still on, taking it out of band. Testing correctly, it did not go above SWR 3 between 222 - 225 . All three bands stay under 3, focus around the 2, and some points get down a little lower. For the trade off of having a tri-band antenna to plug-&-forget with my BTECH UV-2501, the convenience is WELL worth it in my opinion. I also bought the paired magnet mount via this seller, and this is really a convenience. All the parts appear to be of quality and sealed correctly. Also, there are 3 points of adjustment on it for very small tuning. The angle-adjusting mechanism is quite good, as it remained recessed inside the spring loaded base unless needed, so it won't blow over in high winds. That being said, if one does want to angle it,, it really only allows an angle grater than about 30 degrees. If the angle is too small / acute, it is simply snap back into the base. I am sure there are ways to apply a kind of 'cast' if one wanted. ## Features - Effortless Installation and Omni-Directional: The Nagoya TB-320A is designed for easy setup, making it accessible even for those new to radio equipment. Its omni-directional capability ensures that it picks up signals from all directions, providing consistent and reliable communication. Measuring approximately 38.5 inches, this stainless steel antenna is both robust and efficient, striking a balance between size and performance. - Ready-to-Use with No Tuning Required: One of the key advantages of the TB-320A is its readiness for immediate use for Amateur users, as it requires no additional tuning. This feature saves time and makes it a convenient choice for users who prefer a plug-and-play experience. It is ready to work on the 2 meter, 1-1/4 meter (220), and 70-cm amatuer bands. - High-Quality Construction: The antenna boasts a satin finish, enhancing its durability and aesthetic appeal. It also features a gold plunger-type contact pin, ensuring a superior and reliable connection, which is critical for maintaining consistent signal quality. - Convenient Fold-Over Design: The TB-320A features a thoughtful fold-over design, allowing the antenna to be easily lowered in environments where height is a constraint, such as parking garages or under low overhangs. This design aspect adds a level of practicality, particularly for vehicle-mounted setups, ensuring that the antenna can adapt to varying spatial limitations. - BTECH is proud to be in the USA, which allows you to have the best available local support for any issue that may arise.

It says "Grounded" metal plane, does that mean metal has to be touching the ground (earth) or is a metal object on roof ok?** A: "Grounded" metal plane depends on what band antenna you are talking about. For 2 meter and higher frequencies with mobile applications on vehicles, the metallic vehicle body serves as the ground plane. The antenna needs a 1/4 wavelength radius circle of metal at the base of the antenna to serve as a ground plane. This is easily accomplished on most vehicles. HOWEVER, the lower in frequency you go, the more difficult this is to obtain. As a result, antenna tuners may be needed to tune the radio to the antenna. Base station antennas are either of a vertical or horizontal design/polarization. Most HF verticals need a ground plane under them, usually buried under ground. Horizontal HF antennas do not usually use a ground plane if they are mounted at least 40 feet above ground. VHF/UHF antennas, both horizontal and vertical, usually use the metal mast it is mounted to as a ground plane. Horizontal beam antennas also have their own builtin "ground plane" in the antenna design.. Height above ground for these antennas is not important, EXCEPT if you are trying for more coverage area. **Q: The title says "144/430" but the description says it will go up to 520mhz?** A: It will work there, but not at top efficiency.. Most likely the antenna is tuned for the middle of the 440 band (430), and the middle of the 2 meter band (144).. **Q: Will this work as a base station antenna?** A: I don't see why it would not work. It's better than the small 'rubber duck'. However you may wish to consider a physically longer unit 1-2 meters (3-6ft) antenna that can be permanently secured. **Q: Is this antenna waterproof and can it take the hot sun during the summer time?** A: I live in extreme Northern Maine on the Canadian border on the US side. We get temperature extremes -50 in the winter and we can certainly get up to 95 in the summer. Mine has served me well in all weather extremes, and I am about to purchase another one, not that mine is broken, but to add a second radio for APRS use. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good, solid, economical antenna *by G***N on September 16, 2017* A quick review of this tri-band antenna... Fit and finish: Excellent. It ships with the section above the center coil removed. A hex key is enclosed to tighten after inserting. You can't put it in too far, so there's no adjusting. It also comes with a chromed UHF to NMO adapter, also finished nicely. I don't believe other manufacturers include one of these, so if you were to buy a UHF-mount tribander from the "other" guys and decide to go with the tried-and-true Motorola mount, you can add about $10 to the cost.

Last one I had survived on the back of my truck until it was wrecked by a piece of equipment in the bed, Otherwise its a sturdy antenna that's easy to mount and looks good on a vehicle. ## Frequently Bought Together - 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 - BTECH UV-25X4 (Second Gen.)
