Any one know where to get a fitted antenna male connector for Nat01

Try Farnell or RS Components. They should have just about any Coaxial RF or Belling Lee connector you desire.

Try searching www Belling Lee & look into the images section,  you have more plugs,  adaptors & ready made cables than you can believe existed  -  a picture paints a thousand words.    

I'm guessing he may not be living in the UK ..........

 If it is like my NAT05XS, I found it has a male PAL/Belling Lee terminal.  I was surprised by it not being female.  I was able to find a female PAL to American F-type adapter at the river.

Getting a PAL adapter is worth the trouble vs forcing an American push-on to get the job done.

Dear David,

you are right, and I am from Taipei of Taiwan. I tried Farnell but it is out of stock and manufactured. Is there any way to find one?

Hello Tom,

If you go online to a hugely popular auction website, add .co.uk on the end of the name (instead of .com or whatever) to use the UK version, search for "female tv aerial connector" and it should come up with plenty of options, which will hopefully post world-wide.

Dear Blythe,

i use same female tv aerial connector as you suggested, but the male needle just too thin to fit into nat01. I hope Male Billing Lee/ coaxial terminal may perfect fit, as the diameter may around 2.4mm.

The Belling Lee dimensions are a universal standard.   Are you confusing a Belling Lee (CoAx) male plug with an F type plug 

Yes, dear Mike. "Male CoAx with Female F" is the one I use now, cause I cannot fine any Billing Lee RF. The needle diameter is too thin to fit into nat01, which is not well fit.

TomYang,  as I said in my previous post,  the Belling Lee CoAx is a fixed internationally agreed size. If you do have the correct Belling Lee male & its pin is too small for the female Belling Lee receptacle on the NAT-01,  then the female receptacle on the NAT-01 is misshapen (distorted).

I found my NAT05XS male terminal had a misleading hole in the middle pin.  Use a female B-L to plug, with larger diameter hole in its pin/sleeve, to plug into the NAT — perfect fit.

Nick

All the more confusing because my NDX-FM has a female F-type terminal!

Nick

To the best of my knowledge, all Naim FM tuners supplied in the UK, have a male co-ax socket on the rear panel, which requires a female plug to connect your coax aerial lead into.
I suppose it's possible that the socket has been swapped to an F-type or another type of connector during its life.
Perhaps TOMYANG might like to post a photo of the socket fitted to the rear panel of their NAT01 to confirm what is actually fitted?

The upper set photo is exactly the same rear penel of my nat01. I now use Male CoAx to fit in, and it won't work well due to the diameter of the needle is a bit small.  I have no way to find Belling Lee RF here in Taipei.

I'm very surprised at that.  The Belling Lee type connector must be one of the most common aerial connectors out there.  Surely even in Taipei?

It may be that the female connector has got worn and the centre section has got too splayed through age and use.  You can try to close it up a bit with some needle nose pliers (be very careful as it's easy to overdo it and break the connector) to get a better connection, but otherwise it probably needs to be replaced, which is sometimes down as part of an overall service.

Dear Richard,

After consult former and former Naim dealer, he said only ONE nat01 was sold during his time of dealership. He cannot recall , 25-30 years ago, what the connctor look like as it was packed with antenna cable. Really just few knew Belling Lee RF  aerial connector, even I called Taipei famous Electrical component dealer this morning. 

Is there anyone can buy one for me to fit nat01 with CoAx, there in UK?

TOM

This is what I am used Female F to IEC male. The diameters of needle and out ring just a bit smaller than what Nat01's outfit, which made anetnna not well received.

TOM 

OK you have answered your problem.  Belling Lee,  or IEC as you call it,  are the same.   If the pin is too small that means the female socket in the NAT-01 has become misshapen,  its what both Richard & I told you in previous posts, it can happen over time with many in/out connections.   It can easily be re-shaped to fit correctly,  if you are afraid to do this then take it to a radio, TV or electronics repair shop,  any service technician will do this. 

The hole in the male IEC on the NAT pictured is what is confusing.  It suggests it is female, which is the mistake I made.  Try using a female IEC to plug into your NAT.

Adapters from F to IEC are available online in every possible combination, even though IEC/PAL/Belling-Lee is uncommon in the US.  You can combine adapters, if you have to, to reverse the gender.

The fact that when a terminal on a radio or TV is F-type, as it usually is in the US, it is female, further confuses people like me who are not familiar with IEC.

Nick

Thank you, Mike and Richard. I pressed the female pin socket and outer ring both inward. And now my male ICE is fitted tighten. Eventhough I am not sure how much % the surface increased, the loosen situation did improved.

thanks for advise, dear friends.

Hi again Nick, yes its confuzzin' all right & not helped by the NAT-05 with its hole in the middle of the pin.   The plug config on the various NAT's varies:   The NAT-01 has a female socket / male plug.  The NAT-05 has a male socket /female plug.  

I've tried various adaptors on my NAT-05 using combo's of F type & IEC (BL) ,  eventually settling on a 90 degree entry using a wired IEC plug (not an adaptor)     

Thanks, Mike.

Interesting that NAT01 uses female terminal and my NAT05XS uses male terminal.  Fuzzy image above made it hard to tell.

Helluva “standard”!  

????

Nick

Dear all,

UK Male Belling Lee's spec is pin diameter .235 cm outer ring .952cm inner ring .820cm.

It is different from IEC's 0.21,0.94, 0.82 cm. It may be the main reason why connector loosen and not fit well. I have order few connectors from US Texas ML seller through eBxx, and will update you once received and installed.

Very neat MIKE-B  

What is that little black box between the antenna input and line output?

it’s a ferrite clip on.   it’s a pic taken during a time i was experimenting & it now lives elsewhere.
