A cableman said he heard me radiating a block away. he came in and changed 7 crimp type connectors in my attic a couple of cable runs.

Yep, that's the way it works. *Compression type F connectors work well. *Crimp type are junk. *The catch is that there are probably 100 different types of connectors, each with their own compression tools, intended to fit about 8 different types of 75 ohm coax (RG6a/u, RG59/u, single shielded, double shielded, quad shielded, direct burial, etc). *Mixing connector types and cables doesn't work. *I got fed up and "obtained" a 1000ft roll of double shielded RG6a/u, a big of matching F, BNC, and phono connectors, a compression tool, a stripping tool, and replaced all the junk cables in the house. If it's Comcast, you will probably still have the lower 72 channels doing analog. Remove the set top box and plug in your TV directly. Oh, if that is the fact, I may get me some browny points, If I can get the signal up to snuff, then put the vcr back in the line, my wife could record her soaps again. That would get me 15 seconds of hero status! Mikek I'm sure it's true for Comcast in Santa Cruz, CA. *No clue on other areas. *The grand plan is to move all the analog channels to digital area by area: http://www2.insidenova.com/news/2011/jun/22/comcast-removes-scores-ch... http://www2.newsadvance.com/business/2011/nov/09/comcast-switching-an... Unfortunately, your area may be one of those that have moved to all digital. *Hard to tell from here. Just an addition to the termination debate, the marina has about 150 taps, I'd be surprised if 30 of them are connected to a tv and the rest are unterminated. The line generally goes to the utility pedestal into a 2 way splitter and then about 1 ft of cable connects it to the 2 taps for the boat owners. * * * * * * *Mikek Can you determine if the marina is using a distribution amplifier driving a big splitter, or is using a single cable trunk snaked through the marina, with taps (directional couplers) at various points? *If taps, it's easy to install too many taps, or miscalculate the tap type, resulting in level variations along the trunk. http://www.doityourself.com/forum/entertainment-center-tvs-stereos-vc... -- Jeff Liebermann * * 150 Felker St #D * *http://www.LearnByDestroying.com Santa Cruz CA 95060http://802.11junk.com Skype: JeffLiebermann * * AE6KS * *831-336-2558 Jeff, I installed TVRO systems for several years and used a lot of F connectors. Suprisingly the ones I found that worked best were the ultra cheap ones that only took a pair of pliers to fasten These were the ones with the separate crimp rings. Used with some good quality heat shrink tubing this eliminated most of the problems you mention. I dont know why these connectors went away, my only guess is that someone wasn't making enough money on them. Jimmie Jimmie |
