Diamond X50N on PMR

Has anyone used one of these antennas on the PMR446 frequencies? I am curious as it says that the bandwidth is 430-440Mzh, but I am sure I have heard others saying that they still work ok and that the SWR is acceptable.

Yout thoughts would be welcome.

Hey up Simon and I use a Comet GP1 very similar antenna and the SWR on PMR is spot on

Thanks Craig. I know that in an ideal world the X50NA would have been the version to buy but we cannot get them over this side of the pond.

the difference in SWR readings on 70cm and 446mhz is minimal.

One of the guys I chat to locally on PMR is using the X50 and I recently purchased the X30 myself at the recommendation of one of the other chaps I speak to as they give both antennas glowing reports! My own is still to go up on a chimney lashing kit, it is finding an installer at the moment I am struggling with as my days of climbing across rooftops are long past.

Thank you Alan. I am going to give it a try once my coax connectors turn up. It has to be miles better than the rubber duck on my H/H

Without a doubt it will be, I was advised to swap the rubber duck out immediately on my handset and have done so with each one I have bought noticing vast improvements over the original rubber duck. The standard one I am using on handsets is the Nagoya NA771 and I have purchased one of the goose-neck, folding tactical antennas, which, when out with the dog I was able to hear a cruise liner make its various stops around the coast on one of the Marine frequencies I was listening too at no less than 4 of its coastal pick-up points.
After joining the local group of radio operators I have found the majority who are using PMR have a mobile unit set up as a base station and even though I, like you, got all the connections for my handset(walkie-talkie) I have ordered one myself due to the various benefits it can offer although my handset accompanies me every time I go out with the dog pretty much!

I do have a Nagoya NA771 and use it regularly although I am thinking that it could be a fake. On 446 it doesn't really work any better than the stubby rubber duck that my Bumfeng came with. I also have one of those micro mag antennas for the car, but again it isn't great on performance. that could be down to the crappy coax it came with though...

I am too far inland to pick up much on the Marine band but I have listened in whilst at the coast a few times.

It may well be fake as I tried them all out making comparisons which went as you would expect the tactical one does best by far followed by the Nagoya then the standard one it shipped with, especially over distance I found.

My brother bought it for me and he just bought the cheapest he could find, it looks good enough but I'm almost certain it's a fake.

We have all been caught out with fake products back and forth, they look the part but more often than not have poor functionality, it is only then that you start to suspect they are a copy.
If you buy from a UK supplier you may pay a little more but are far less likely to get caught out with a fake but in saying that I just looked at others from abroad and some have very good reviews indeed and if I wasn't in a hurry I would be tempted to try them myself with prices like that.
I bought each radio bundled with the Nagoya antenna and recommended a some friends I have helped purchase/program their sets do the same and we have had no problems when I have purchased another I just ensured it had a decent write up from other customers.

A GENUINE NAGOYA NA-771 will have a tiny inverted triangle inside the letter "A" on the base (see photo). If it doesn't have this then its a fake (this information is from the manufacturer's site).

In that case it is definitely a fake. Thanks for the info.

Hi i use my X30 for PMR and it works really well.

i got my base antenna from Slovakia home made and its great and i have a home made with measurements from tm 01 and its into a 3/8 onto a mag mount and gets out well some say 1 to 2 max range i get further at home and lots further out mobile static next week if its like this the weather, will be out with pmr and my superstar 6900n and the t2lt antenna and try for some contacts
