75 Ohm connector on back of Phillips DVD surround system - w

[David Forsyth]

Hello,

A friend of mine has a Phillips DVD / surround system that he bought for
cheap somewhere. It has an FM tuner in it, and the FM antenna input is
labeled 75 ohms, but the connector is not the standard 75 ohm coaxial "F"
style. I suspect that it is either a proprietary style that Phillips uses,
or more likely a European style that we don't generally see here in North
America. It has a push-on type (unthreaded) outer ring about 10 mm in
diameter. There is a hollow center pin of about 2.5 mm in diameter. I am
looking for a way to adapt it to the "F" style. Does anyone know what this
connector might be, and who makes an adapter for it?


thanks,

Dave

Dave, I suspect the antenna socket is a standard 75 ohm PAL coaxial
socket similar to that shown on this page
http://www.arlec.com.au/EnlargedPic.asp?PageNumber=1&Product=40

You will need a "F" female to PAL male adapter similar to part #1113
shown here http://www.universal-radio.com/catalog/parts/f.html

I had the same problem last year. I asked here and they gave me a
strange name, but it's generally called a Euro connector and I got the
adapter from Radio Snack. Here's a URL. I believe it's the 278-265.

I put brackets on the above URL to see if it helps with the wrap
problem. i don't think it will, from past memory.

thanks,
Dave

Hi all,


I thought it might be a PAL connector, but I couldnt find any exact specs or
good pics of one to verify.


many thanks!


Dave

It did as you should be able to see.

However, you have the wrong item as that is the same as the socket
on the receiver with a hollow pin. The one you need is 278-261 which
has a solid centre pin which guzzinta the centre hollow pin of the socket.

They were designed in the UK in the 1940s. The proper designation is
"RECMF" (Radio and Electronic Manufacturers' Federation), but they were
generally known as "Belling-Lee", since that's who made them. They also
occurred on some UK made mobile radio gear that I crossed swords with in
the 1970s, despite their being nominally 75 ohm. Usually made of
aluminum. IMNSHO, they're crap.

Sounds like the standard antenna connector used in Britain (and
Australia?). I've always known them as Belling Lee connectors. They
are usually really cheap and nasty but I've been told that they are
actually a very good impedance match - far better than the "UHF" or
239 connector.

For those non-natives, these are called PL-259 and SO-238 here in the
'states'. PL meaning plug, and SO, well you can guess that one.
They can handle a kilowatt, but I wouldn't push a 'Belling-Lee' that
far.

You can get varying degrees of quality of the Belling Lee connector
from different manufacturers.

PL-259's and SO-238's are also known by those names here in Australia,
as well as probably most parts of the world.

Those were originally military designations so everyone would use the
same name even though they were replaced by newer designs on military
radios.
