I can assure you that PAL refers to an analogue broadcast standard. What the
Americans call a "PAL connector" is really strictly speaking a Belling Lee. It sounds like "PAL connector has become everyday language in USA, just like "Hoover" or "Xerox" whereas strictly speakign they are vacuum cleaner and photocopier respectively. Here in Great Britain, the F- connector is used for connecting satellite dishes to the recievers or by the cable TV networks. I persoanlly prefer F connector to Belling Lee as the latter can easily fall out of the socket whereas F connectors dont. Stephen. "Geoffrey S. Mendelson" wrote in message ...

Isn't it just a push-on non threaded F Connector? No, the center conductor is too fat. It's an ordinary RCA plug, but with the solid shell to impress the audiophools. The push-on F connectors I have here have the slotted shell, but the center conductor is about 22 or 24 AWG and there's a springy loop around the shell leaves. Hope This Helps! Rich |

What the Americans call a "PAL connector" is really strictly speaking a Belling Lee. I think it can be two things at the same time, and it's hard to be just a Belling Lee when I for one had never heard of such a thing. I'm sure that's true of many people who sell them in the US too. It sounds like "PAL connector has become everyday language in USA, just like "Hoover" Hoover means vacuum cleaner in some other countries, but in the US it's just another brand. Gerber means baby food in general some places. or "Xerox" whereas strictly speakign they are vacuum cleaner and photocopier respectively. Xerox does indeed mean photocopy here. I think a small part of my jaunt in law school dealt with trademarks, but I've always thought the rule was backwards from what it should be. If people use xerox as a synonym for photocopy, that should strengthen the trademark and not weaken it. Then the Xerox company, or the Scotch tape company wouldn't have to waste their efforts defending their name, except in advertising for another brand. But when someone actually uses a Xerox machine or real Scotch tape, making them call it Scotch brand tape or Xerox brand photocopying seems silly. And if someone on the news, for example, said the company released a xerox of some document, just assume they used a real Xerox machine or something living up to its standards. Just my rant.

wrote: Thanks. I've got a dual tuner card from a thrift shop that has those connectors, so you've just helped me out too. Y'er welcome. I had never heard of Belling-Lee connectors until some friends arrived from UK with "universal" AM/FM/TV/SW contrivance that did PAL, NTSC, and SECAM all in one box. I wanted to see how well it worked, but when I tried to plug in a test cable, I couldn't find a connector that would fit. The manual was useless. The local shopping mall travel store was helpful. They allowed me to dig through their collection of connectors, where I found one as part of a very expensive adapter kit. A few photos and a dumb question in one of the travel forums generated the necessary info. However, I didn't want to wait for an adapter, so I made my own from some brass tubing and an F connector. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

wrote: The push on connectors were the 'G' series, and designed to be matable with the 'F' series. Not exactly. The "G" series was contrived to provide a connector suitable for passing up to 15A of current. The cable companies have always powered line amps from DC on the cable. That was fine with semi-rigid coax and compression connectors that could handle the current. However, when the amps shrank in size, a newer smaller connector was needed. That was the Type G connector. http://www.amphenolrf.com/products/typeg.asp?N=0&sid=4DBB51003571617F& Most places selling them are absolutely clueless, like selling DE9 connectors as DB9. Mass marketing to, for and by idiots. ![]() Well, lets see what Google can offer. Searching for DE9, I get 70,100,000 hits, while DB9 returns 8,830,000 hits. So about 12% are clueless. Actually, it should be DE9S or DE9P, but that's being picky. If you want real fun, try to buy a 'HN' connector over the counter at a wholesaler. ;-) http://www.amphenolrf.com/products/hn.asp?N=0&sid=4DBB510041D4E17F& Hi-V. I've never seen or used one. There are plenty of other obscure connectors. The RF industry is full of specialized connectors. There was one connector found on many wireless cards where I couldn't find a mating plug. It turned out that there wasn't a mating plug. It was a test connector with a conical entry. http://802.11junk.com/jeffl/crud/WG511.jpg -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

And for that matter, BNC twist on, so why are they in this discussion at all (in other posts)? I just learned that B stands for bayonet. I once had a salesman tell me it simply means "Bayonet Connector"; presumably the BN is BayoNet, as in TTY for TeleTYpe. :-) Cheers! Rich |

While I personally think the world would be a better place if everyone standardized on 1.2 volt AA batteries (preferably NiMH at the moment) it's a loosing battle. You would figure that after the battery disaster with the original iPod Apple would have done something better but it seems that their customers prefer internal batteries that need to be replace by a technician or the entire device recycled.

An F connector normally uses the center conductor of the cable -- a wire -- as the center connection -- not an RCA-like plug. The press-on F connectors I've seen use a slotted jacket that usually fits snugly and rarely causes problems. |

In fact Amazon US doesn't have any electronics item with "Belling Lee" in its specification. In the US they are called PAL connectors. http://www.radioshack.com/product/in...ductId=2103468 Geoff. Officially, on both sides of the pond, they are referred to as IEC 169-2, or IEC 60169-2 connectors, and they are CRAP for TV usage as they are not a proper match to 75 ohm cable - actually closer to 50 ohm, and cause reflections and ghosting of the signal The IEC 169-24, or "F" connector is superior for TV use. |

Not the ones I saw in the picture. The center pin is WAY too fat for an F. They're simply audiophool-style RCA connectors with a solid shell that looks "kewl". Cheers! Rich |

"Klay_Anderson" wrote in message The connectors in the photo are "press-on F" connectors. Cheap to make, they simply slide on the chassis threaded F. They are horrible and cause a lot of issues as they do not allow proper and tight sheilding. I don't think that's correct. An F connector normally uses the center conductor of the cable -- a wire -- as the center connection -- not an RCA-like plug. The press-on F connectors I've seen use a slotted jacket that usually fits snugly and rarely causes problems. And are good for about ten or twenty insertions before they get loose. Cheers! Rich |

It was "invented" by Motorola. It's a longer version of the the RCA connector, "invented" by RCA. Probably at one time RCA had a patent on its connector and Motorola had a patent on theirs. It wasn't until the second world war that the concept of standarization across manufacturers was pushed. Companies made their own parts, connectors, etc, and tried to prevent competion. A car antenna connector (AM band) has an "inside-out" shell: http://shop.vetcosurplus.com/catalog...e.php?pID=8818 Hope This Helps! Rich |
