I might be able to find the manufacturer's original part number for you if I searched through the back-issues of Wireless World; but if it is that difficult to find, I don't suppose anyone will recognise it. The characteristic impedance of those connectors was 75 ohms. The last batch I had from R.S. Components, about two years ago, had sub-standard insulation and were mechanically unsound (they fell apart at about the fifth time of use). Needless to say, they hadn't been made by Belling & Lee. -- ~ Adrian Tuddenham ~ (Remove the ".invalid"s and add ".co.uk" to reply) www.poppyrecords.co.uk

Older ones will call them a Belling-Lee, strangely enough. But they are pretty universal in the UK for all terrestrial TV and FM radio aerials, and have been since the outset. Way before PAL was thought of. -- *Beauty is in the eye of the beer holder * Dave Plowman dave(a)davenoise.co.uk London SW To e-mail, change noise into sound.

I recall that my own measurements (in the 1960s) indicated that a genuine B&L connector was actually a pretty good match at UHF TV frequencies (well, up to 500MHz or so) - certainly not enough to give me any concerns that the whole of the TV industry had made a bad choice of connector. -- Ian |
