I am just trying to get an updated list of the top brands of RG-6 quad shield coax cable.

I have seen Carol and Zenith brands at local stores recently, are these any good? Mainly going to use this cable for running feeds from HDTV & analog TV antennas in the walls of a house. My experience with a few Carol Cable products (including coax) has been good. I would consider that the Zenith brand name appears to be rented out to the best bidder these days (peruse a.h.r for recent stories about Heath/Zenith products) and expect that the manufacturer spent most of the cost of making that coax on the marketing of that coax. -- Music hath charms to soothe the savage breast.

I built a component cable set for my front projector out of the Canare V3-5CFB, which is basically similar to the L-5CFB but has three cables wrapped together in a single jacket. Works very well.

I dont question your judgement, but I have found them to be good for my 2 meter application. Now I am considering doing some work at 2 GHz. This is a good time for me to learn about cable and F connectors. Thanks Jerry |

First, I don't find them to make that great of a mechanical connection and can therefore be pulled off the cable fairly easily. Second, and I admit I don't have network analyzer plots to back this up or anything, I've always found them to make a mess of the shields when you twist them. That could lead to more of an impedance bump at the connector than with other types. Probably not an issue at 2 meters, but more important as the frequency goes up. Paul |

First, I don't find them to make that great of a mechanical connection and can therefore be pulled off the cable fairly easily. If you can pull them off, you are probably not putting them on correctly. (Tip: Ignore instructions, and use cunning.)

That could lead to more of an impedance bump at the connector than with other types. Probably not an issue at 2 meters, but more important as the frequency goes up. While the connector thread will crush the outer somewhat (causing a very short piece of low Zo), it's unlikely to be a problem in most applications, even at 2GHz. Ian. -- |

The compression fitting have a captive sleeve on the cable end of the fitting. You strip the cable more or less as usual, slide it up through the connector as you would with a crimp type. But then the compression tool presses the sleeve up into the body of the connector. The inside is tapered, so when the sleeve is pressed in, it compresses against the cable, locking it tightly into place. Here's a pictu http://www.cablestogo.com/product.as...=411&sku=41077 They are also available with seals for water resistant outdoor use. (In fact, the picture is of a connector with seals.) Here's what the tool looks like: http://www.cablestogo.com/product.as...1403&sku=38011 Try 'em, you'll like 'em! Paul OK. It's a large, well engineered crimp tool and fitting. I actually have tools, some cable, and a bag of ends that fit that description. I just considered them standard tools and parts for serious work. They came to me by accident. I was the "customer" for a a pre-ethernet LAN built on CATV plant that spanned a 40 floor building. -- a d y k e s @ p a n i x . c o m Don't blame me. I voted for Gore. A Proud signature since 2001 |

Twist-in connectors do not provide the shielding that a CATV system needs.
They are a HUGE source of ingress/egress, and the return loss is rather low (the higher the better. Hex-crimp fittings have ~18dB, and compression are 30dB). Plus, It actually takes more time to put on a twist-on connector that it does to put on a real connector. Compression fittings may cost a little more for the connector and the installation tools, but cost less in labor (time) to install. Not to mention the materials/time spent in replacing the twist-on connectors with real ones when they don't work properly. -- CIAO! Ed N.
