Hi BM,.. did you ever use this antenna,... if so can you give me a report on it please,..I will purchase two if you think they are any good. Where did you get yours from?, I can only find them abroad, mainly Hong Kong,.. I dont mind buying from there is they are of some use

Hi,

No, I ordered the 774 - which has the wrong attachment, so now I'm struggling to find an SMA male to female connector.

I've just this second ordered this: http://www.ebay.co.uk/itm/NAGOYA-NA-774M...33778ad9fd

which should do the job nicely. Seen reports on the UV-5R forum that these boost your distance by a good 40 - 50%

WARNING: In the context of using UV5R radios for PMR frequencies the Nagoya after market antennas mentioned here are not 100% suitable.

The antenna that comes with the UV5R is matched to the frequency range of the radio. This is a very wide range indeed, and includes the PMR446 frequencies. The Nagoya and many other after market antennas are tuned ( matched) to the Amateur frequencies.

This means that on the whole these aftermarket antennas will have poor SWR matching at PMR446 and Marine Band frequencies. This will both limit transmitted power, impede reception. Transmitting outside of the antenna's designed frequency ranges will result in mismatch with the radio's output transistors and this will tend to shorten the life considerably.

There is one Thai seller operating on e-bay who is selling telescopic antennas that are tuned specifically for PMR446. I have tested these and they work very efficiently, and at these frequencies, considerably more efficiently than the antenna that came with the radio. However they are only suitable for PMR446 frequencies, and are more fragile than the standard antenna. For peace of mind, I stick with the supplied one most of the time.
