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.
