content: Where do you get your BNC splitters, terminators, adapters and whatnot? I've had really mixed luck with this kind of stuff. I just got four BNC splitters - three are open circuited internally and the fourth is intermittent. Not worth returning them because they were so cheap... (Also, if there's a way of opening them to repair that I can't see, I'd love to hear it.) There doesn't seem to be much between "way too expensive for a damn plug" and "so cheap it's broken". I'm not looking for ultra-high-frequency Agilent-branded upper-RF magic, I just want a splitter that bloody works!

content: Y'know, it never really occurred to me to check at good ol' Mouser. I think of them for components, and I don't really think of a cable widget as a "component". They actually have some decent prices, and considering I'm sure to be ordering something from them soon, I can combine the stuff and not have to pay for shipping on the BNC widgets.Amphenol should be decent, right? I never really buy this kind of stuff, but at least I've heard of them.112461 tee adapter46650-51RFX terminatorCan't find a reasonably priced BNC-banana, but I can probably just whack off the end of a spare BNC cable and attach a double banana plug.

content: Pasternack Enterprises carries a huge line of RF connectors, adapters, splitters, attenuators, etc.http://www.pasternack.com/Unfortunately, if you request info, or place an order with them, you will be on their mailing list FOREVER. They apparently haven't heard of email, and I shudder to think how many trees they have killed stuffing my mailbox with their constant mailings over the years...

content: I have some 40 year old Amphenol BNC T connectors, BNC-N and BNC-UHF adapters all in good condition after lots of use. However, these are the old silver plated brass MILSPEC connectors.New "Made in China" connectors have a lifetime measured in months in distressingly many cases. In fact, I've had more than one fail the first time of use and even have a couple that had failure before use -- BNC-UHF adapters where the UHF end was not fully threaded and hence would not mate with the UHF connector.Silver plated MILSPEC connectors are still available, and like high quality hand tools, can be passed along to future generations. But be prepared to pay significant money. For example a BNC M-F-F Tee connector MILSPEC from Mouser is around $18. Look for UG-274B/U adapter, Mouser PN 523-31-2208. A One-Hung-Low Chinese Tee is about 1/10th that price and will probably last about 1/100th as long.Also note that there are two types of BNC MILSPEC Tee connectors, one with three female ports and the more common one male, two female.

content: Life is too short for crap adapters. Moreover, remember that you run the chance of damaging expensive test equipment with poorly made connectors.Here are a bunch from digikeyhttp://www.digikey.com/scripts/dksearch/dksus.dll?FV=fff40016%2Cfff803d7%2Cf0005c%2C16c0180&k=bnc+adapter+t&mnonly=0&newproducts=0&ColumnSort=1000011&page=1&stock=1&pbfree=0&rohs=0&quantity=0&ptm=0&fid=02-7 bucks gets you a T piece. Look for ones that have a mechanical drawing, that normally inspires enough confidence in me.Mouser, RS etc have similar. FWIW I don't like Farnell's Multicomp series - their SMA's are especially cheap, but probably better than any ebay finds.
