Authentic Genuine Nagoya NA-771 15.6-Inch Whip VHF/UHF (144/430Mhz) Antenna SMA-Female for BTECH and BaoFeng Radios

Good and reliable receiving with this antenna compared to the NA-771.

If you looking for a great antenna for your car, loook no further. Outstandingly good reception, especially for airband and will easily withstand legal road speeds without moving. Tested up to 120mph on private road with no issues. Connected to my TD-H3 handheld radio it performs brilliantly.

Excellent reception, audio quality and value for money! SMA connection makes it easy to connect/fit to my handheld radios

Ordered this as it covers the 3 bands, but received the NA-771 instead! OK, I can use it for what I need, but it’s NOT what is described!!

Checked with VNA. It is the real dwal, and as i go to USA 220 mhz useful

Fantastic

As far as I can tell, the antenna I received is a 100% genuine Nagoya NA-771 antenna. I used the guidance at Nagoya's How-to-identify-the-genuine-and-fake-antenna web-page and the item I received matches all the examples for a genuine antenna and sleeve - the printing is good, the sleeve bag is good and the antenna came with a spacer o-ring. I don't have the equipment to test whether it behaves as it should, but when I connected it to my UV-5R handset I was able to receive signals at a fair range, better I think than the stock antenna (but I didn't test it super-hard before switching to the NA-771 full-time).

This is FAR from a high-gain antenna. The power in will be the power out with this design, in theory, in practice this will lower your signal with such low dBi as this antenna has. This is false advertising claiming that this is a high-gain antenna. Does it function as intended? Well no, this antenna cannot possibly create any gain improvements, which the description claims. What it will do is slightly lower your power than the radio outputs. However, it may be an improvement over stock antennas which are usually worse than this antenna.

Excelente calidad y señal, muy recomendable

Kort maar met een redelijk range.

The antenna had different thread spacing and would not attach to my NMO antenna mount. Disappointing.

Very nice unit. Loss is at normal level for vhf/uhf. Would be nice if they use lower loss cable. Yes, make the coax thicker but I could live that.

Got this ground plane kit to test on my mobile rig. Tested this two different Comet antenna. One is a Comet CSB790A and a Comet CA-2x4SR. Both are dual banders. Though these antenna are mounted on a 1"x2" extrusion style rack. Though I have a decent grounding from the rack to the steel roof on my 1999 Toyota 4-Runner. This ground plane kit helps with the SWR a tad bit. On the Comet CSB790A antenna. It's a UHF style and I got a NMO adapter for the antenna mount. So with that being said. I tested the SWR and wattage output from my ICom 2730A mobile radio with the MARS mod using a Surecom SW102 meter and a Sysjoint NanoVNA-F V3 analyzer. One to test the harmonics and resonance of both antenna on 2m and 70cm bands. Both were tested on the 2m and 70cm calling frequency. Was able to make several contacts about 40+ miles away with full quieting. This kit did improve a tab but nut I don't plan on using this while being mobile. This kit best work on attaching the supplied stainless steel bracket to a post or pole using two supplied heavy duty hose clamp where there's no flat metal object to use a ground plane. I haphazardly attached this to my wooden fence and it did to reduce and lower the SWR quite a bit. Everything helps when you're trying to make that connection either simplex or trying to hit that long distance repeater long distant away. Also Nagoya said you can use this while mobile but my highly not the SWR don't help much or at all. But word of caution is that if you wish to use this while driving. I would recommend use medium strength thread locker on the hardware before you start driving. Great ground plane kit with no issues other than the set screw is small. I almost 4 of them. I would recommend this to any mobile HAM operatiors especially when you're at park with just a wooden post or tree you can attach the bracket to.
