N plug solder for semi rigid


militaryoperator
 


Looking on ebay, can't find a UK supplier of N plug for semi-rigid, soldered. 

They all seem Chinese or Crimp.

Where to go?

Jyebao make quality connectors and their Taiwanese origin should not lead to assumptions that they'll be like those available from suppliers in the huge country to the west of Taiwan.

Looked there, wow, £6 shipping cost for one plug. 

Thanks Doug.

That's a good site! They appear to do plugs for .250 semi rigid as well ... very useful!

Try F.C. Lane (aka Lane Electronics). 

01403 790661

They are distributors for a wide range of connectors.  They are much cheaper than resellers.

Hi Ben

 

I suggest you try Andrews as they are quite helpful to amateurs

 

From my experience Fc lane specialise in mule pin not coax and have a minimum order cost

Hi Stephan  

 

I should have included Farnell, Mouser, Digikey  who I have hade very good dealings with

And Farnell for over 45 years   M0MAT is new to me and possibly others  can you please highlight there rang / key items  ?

 

Ben you can try RS as they used to be good on RF connectors  ONLY go for the brass or stainless steal body  and steer away from any think chrome plated

In the old days the ones branded RS where good connectors  but sadly times change

They are an (probably only) UK distributor for Huber & Suhner who make RF connectors. I know H&S connectors are not cheap - and in my opinion are over-rated. But when I want hermetically sealed N sockets, F C Lane could supply them from H&S. 

They may have a minimum order. Carriage  is  is about £6 too.

Dear Ben,

This is now a bit of a challenge.

Tyco moved their production to China and the designs are different from the ex-Greenpar ones.

There are many distributors of N connectors who are selling parts with poor design/poor tolerances- I have measured these and they show worse return loss than what used to be available.

Huber and Suhner are good, also Telegartner as a lower cost option, if they meet your spec.

Radiall have moved the production of a lot of their N connectors to China. I have measured some samples of these and they are within spec.

Cinch have introduced some low spec. ranges, check spec. carefully.

Likewise Amphenol.

So, I think you now have to check spec. very carefully, and do n’t be surprised if a connector that meets the MIL spec. to 12 GHz or 18 GHz is quite pricey.

So far as I know, there is no longer any manufacture of N connectors in the UK.

Regards,

Alwyn G8DOH

Dear Keith,

Coax-connectors are indeed UK based. I do not know where the connectors they sell are manufactured.

I note that performance data for the connectors they sell is not on their web-site, but has to be requested.

I have tested a few samples of their N connectors. I measured the return loss to be higher than for equivalent connectors made by Radiall, which are, of course more expensive.

A coaxial connector requires precision mechanical engineering and stringent materials selection- these do not come cheap.

When the applications for these connectors were primarily military, MIL-spec. connectors were commonly available and purchasing was straight-forward.

Those days are gone, so care is required, particularly for use above 1 GHz.

Regards,

Alwyn

Hi Keith  

 

I thought the request was for N connectors  for semi rigid

 

On looking at their web site www.coax-connectors.com I can only raise the following

 

BNC Adapters rated at 18 Ghz    when the construction of the BNC connector causes issues at 1.4 ghz  so any professional would limit them to 1000 Mhz and usually 500 Mhz

Please note the TNC is a different connecter when it is used above 1 Ghz as it outperforms the BNC

 

PL259  connecters  are listed UHF connecters  and 50 ohm    they do not have a fixed impedance  but to their credit  the technical spec rates them up to 300 Mhz  but  even at 140 mhz  they can cause large SWR mismatches

 

The Belling lee coax connecter used on domestic TV  are called PAL  or euro connectors    please where did this name come from  ?  we should Preserve the British names

 

I would love to test their right angle N connector  as it is rated at 18 Ghz   as most right angle connecters suffer with problems below 10 Ghz  and so are not suitable above 7 Ghz

 

I realise others might not agree  but you have to have checked connectors using test equipment not just used them  

 

Regards Paul

Hi Paul & Alwyn

 

All points are very valid and noted, I have used Coax-connectors both myself and at work and have found them to be very helpful. The connectors we have used have been tested and met the specs that were required and worked without issue for us.

I realises that there is much more to connectors than first thought but as the question was asked I thought I would mention their name as a possible source, but it is up to each person to decide if the connector in question is suitable for their requirement.

Finding a reliable source of good quality connectors no matter the price is not easy these days.

Dear Ben,

Yes, my thoughts too. I was once looking for female-female in N, and tested every one I could get my hands on. The results were surprising.

H&S had the worst RF performance, but the threads are very well formed. They were made in China. I was just about to phone H&S until I realised that it actually met the specification.

A cheap Chinese one that someone sent me for free had the best RF performance. However, the threads looked like they had been cut with an axe.

The Telegartner, J01024A0004, available from RS

was the best I found in terms of a compromise between RF performance and the quality of the threads. 


There are many distributors of N connectors who are selling parts with poor design/poor tolerances- I have measured these and they show worse return loss than what used to be available.

Huber and Suhner are good, also Telegartner as a lower cost option, if they meet your spec.
 
I guess it depends on the exact connector, but for what I wanted, f-f thru, the H&S had a poor specification, which it did meet.

So, I think you now have to check spec. very carefully, and do n’t be surprised if a connector that meets the MIL spec. to 12 GHz or 18 GHz is quite pricey.
 
So far as I know, there is no longer any manufacture of N connectors in the UK.

There seems very little RF engineering in the UK compared to Germany or the USA, even when taking the different populations into account.
