survtech 0 Posted January 10, 2010 tweak e. you are in new zealand and i am in the uk. i have not used screw on for a few years. i use the crimp 3 piece. but in america screw on is the standard. plus screw on have been on the market alot longer than crimp and as far as for amateurs. you still need to trim screw on just the same way as crimp. Not hardly. Although I admit that some here use twist-on connectors, many dont; including pretty much every casino I've ever been to! Share this post Link to post Share on other sites
RollSound 0 Posted January 10, 2010 Fwiw, working in the broadcast industry, I never see compression fittings. It's always 3 piece crimp. Ymmv. Share this post Link to post Share on other sites

tweak'e 0 Posted January 11, 2010 i'm used to F connectors rather than BNC. but i havn't seen 2 piece F's on the shelf in 10 years. you still need to trim screw on just the same way as crimp i do them different. twist/screw on's you strip the cable like your doing a belling lee plug. the single biggest fault with both twist and crimp plugs is lack of shield length due to installers useing speed strippers (cuts outer and inner core in one go). a lot of the time the crimp misses the shield and you have a low pressure crimp and a shield thats loose inside the plug. with high frequency signal (UHF/IF) the losses are low, but with low frequency signal the effect can be huge.

kensplace 0 Posted January 11, 2010 Only ever used 3 piece crimp myself, never seen the other types at all, other than on forums. Share this post Link to post Share on other sites
RollSound 0 Posted January 11, 2010 That could be but the cable TV industry has used them for years! @ the headend or in the field? I see compression F fittings all the time, but I've never seen a compression BNC used in any pro video applications. Just new to me, if so. Share this post Link to post Share on other sites

Just new to me, if so. what do they use then....an 'f' fitting then an 'f' to 'bnc' adapter? Share this post Link to post Share on other sites
survtech 0 Posted January 11, 2010 They use compression F connectors. For BNC's, I don't know. I have seen some head ends using compression F for patching. I can relate that compression is the only way to go with mini coax; three-piece just don't hold very well. For RG59 or RG6, three-piece work quite well, but I would still recommend compression for outdoor use. Share this post Link to post Share on other sites
Soundy 1 Posted January 11, 2010 Just to toss in my couple of cents... I much prefer compression as well, mostly for their convenience, but they can be a little picky when it comes to stripping the wire (depending on the connector, at least, some are pickier than others). Nowhere near as picky as twist-ons though, and with twist-ons, your wrist gets pretty darn sore if you need to do more than a few patches. Two- and three-piece crimp-ons are what I see the most, and we tend to use them just because they're cheaper, but dealing with all those separate pieces (especially the three-piece with two or three center pins) can also be a pain in the arse, especially if you have to terminate multiple connections in a tight or hard-to-reach or high-altitude space, or anywhere that there's little or no room to stage things out. Plus, all the multi-piece crimp-ons I've seen put each connector in its own little baggie, which adds an extra level of annoyance, especially when in tight spaces. For my money, compression is the way to go. Share this post Link to post Share on other sites
