Making my own coax cables
I would like to make my own custom-length coax cables. What are the
best cable cutter, stripper and crimper for the money? (I'm assuming three seperate tools here). I don't want to spend too much money since this is just for around the house and not pro, but I don't want cheap junk that's a waste of money either. |

BNC, F, Type N, SMC, Mini UHF, TNC, or ? F BTW, Cable does make a difference. I now prefer Belden 7916A RG-6/U for backbone coax runs in a house from cable or satellite drop point. It is swept to 3 GHz .. great for any future bandwidth expansion. a.. 18 awg solid bare copper center conductor , the best choice for baseband thru broadband applications Many CATV companies are installing coax that has ratings at least 2 GHz swept. I use to use Belden 1189A (which is good to 1 GHz - 18 awg solid copper covered steel center conductor) Don't remove copper covering from steel inner conductor) For RG-59/U small runs - Belden 9275 is good !

Making my own coax cables
Travis,
Thanks for the links. I picked up a good Data Shark round cable cutter at Fry's yesterday for only $6. I also got a cheap, generic crimping tool for $7.50 just to see how they work. I tried crimping on an F-connector yesterday for the first time. It took several tries and I cracked the sleeve on the connector on the first try. I don't have a stripper yet so I'm still manually stripping the sheidling. They had an "RCA" brand stripper for $20 that I almost got but it looked the same as the one you posted for only $10 so I think I'll get that one instead. The F-connectors I got have really short sleeves and the inner tube thing that fits onto the dielectric is smallish. I've seen different types of F-connectors and some of my coax cable (labeled Belden 8228) has a larger diameter dielectric. So I guess I'll need to get some different F-connectors.

Making my own coax cables
In article .com,
says... I would like to make my own custom-length coax cables. What are the best cable cutter, stripper and crimper for the money? (I'm assuming three seperate tools here). I don't want to spend too much money since this is just for around the house and not pro, but I don't want cheap junk that's a waste of money either. For my basic home TV cable use, I just use reqular wire cutters for the cable. For stripping and the F connectors, I have a Sargent 8600ESC (for RG6 and 59). It strips the end, you put on a Snap-N-Seal type connector, insert it into a holder, and screw down a little thumbscrew to push it on. -- If there is a no_junk in my address, please REMOVE it before replying!

Making my own coax cables
Home Despot has a nice cutter/stripper and crimp tool set for about $26.
Works well on RG-6 and 59. Completely redid my cable system with them. Use only the gold terminals, spltters and crimp barrels, and high quality coax cable.

Making my own coax cables
JR North hath wroth:
Use only the gold terminals, spltters and crimp barrels, and high quality coax cable. Very bad idea. Gold is great for corrosive or marine atmospheres. If you live in a salt fog, then gold connectors are the way to go. However, there are problems. You must use gold on both the plug and receptacle. Mixing a gold connector with a tin, nickel, cadmium, or solder plate, connector will result in enough electrolysis to trash the non-gold side in short order. If you're supplying gold plugs, but the customer has a device with non-gold receptacles, there may be problems. Gold is also only good for "dry" loads that do NOT carry any DC. This is correct for most CATV applications, but not with DBS dish receivers. These have DC power to the LNB going through the coax. Connect and disconnect a gold connection with the power live and a load, and even the small current will blow a hole through the gold plating. The bad news is that this also applies to ALL parts of the connection. Tin plated coax braid and aluminized mylar shields will act the same way as a mismatched connector material selection. To do it right, literally everything has to be gold or there will be electrolysis at the junction. Since nobody makes gold plated RG-6/u cable, I suggest you forget the idea of using just gold plugs. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

The "gold" plugs you find at the big box stores are more "goldeny"
than anything else. I'm not convinced that there's any gold in them at all.

Mike Berger hath wroth:

Well, I have a few of the consumer gold connectors around. They don't tarnish so I presume they're really gold plated. MIL-G-45204 spec connector plating is mostly 50 microns thick. Cheap commercial flash plating goes down to perhaps 5 microns. I couldn't find any specs on the consumer variety other than most claim that it's 24k (pure) gold. Anyway, it really doesn't matter with RG-6/u because the all important center conductor is bare copper. There is no center pin on an F connector as it's just an extension of the coax cable center wire. All that nice gold to make a better ground connection? -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
