I use a PPC EXXL-6 connector that works with all varieties of rg6 from regular dual, trishield to quad shield. Quad requires a special stripping procedure.

Stripping and installing connectors on Coax

Careful preparation of the cable end is very very important, especially with quad shielded cable. Sloppy preparation will result in failure to set the connector properly.


1. Strip off the outer jacket of the cable and a portion of the center conductor as instructed by the document provided with the stripper.

2. On quad shield coax, carefully fold back the outer shielding wires against the outer jacket of the cable evenly, exposing the inner shielding wires.

3. On both tri-shield and quad shielded coax, carefully cut away the outer foil shielding layer, and remove it to exposed the inner shielding wires. This will not need to be done on regular coax.

4. Carefully and evenly fold back the inner shielding wires evenly against the outer jacket.

6. Place the connector on the stripped coax, making sure that the center insulator enters the inner tube of the connector with "only" light pressure. If it requires heavy force initially, the insulator is not entering the tube correctly. The connector is fully inserted when the center connector is level with the end of the connector, when looking inside the nut.

7. Crimp the connector with the proper hex crimper or compress the connector on the cable with the proper compression tool.


Reasons why the shield wires must remain intact and must be folded over the outer jacket.

A straight cut of the outer jacket and the shield wire layer(s) down to the center conductor insulator will not allow full contact and retention of the outer shield. The shielded wires must be folded back over the jacket. Not doing so means that the connector is just slid over the shield wires and outer jacket and retention of the shield wires are held by friction, not by tightly held tension. Tightly clamping the ends of the shield wires prevents degrading the electrical contact of the shield wires, which serves as one leg of the voltage switching circuit for the multiswitch or lnb of 15-18 volts. If you are passing only a RF signal, it is not a problem, and might not be a problem for short coax runs. But on long runs, any minor bit of corrosion or separation of the barrel from the shield wires might lead to failure and a resultant voltage drop over time. This will manifest itself in the lost of the even transponders in the signal.

The industry standard is the 1/4"x1/4" strip on the coax. If the center insulator is below the center hole in the barrel, the coax has not been fully seated. Ideally, it should sit about 1/16" or 2mm out of the hole. If you a using a compression tool that applies pressure to the inside of the connector, the plunger will force the center conductor almost flush. Over time it might return to the 2mm protrusion. This protrusion is ideal in that it eliminates the "air" gap between the center conductor insulator and the female socket port. The "air" gap increases the chances of water vapor entry and corrosion. If you look at an F81 female port carefully, you will notice that it is recessed about 1/32" or 1mm.

So, folding back the shield wires enhances the electrical contact surface between the shield and the barrel of the connector. It also increases the connectors resistance to pull off. The bent over shield wires clamped by any type of connector prevents "pull off" and ensures the integrety of the connection for passage of both the RF signal, and more importantly, with dbs, the free conveyance of the lnb switching current.

Mike500,

Big fan of your posts, you have some of the best, most detailed posts I've seen, you should write up a FAQ.

I am not an installer, but I copy/paste every post of yours for future reference. (hope you don't mind)

Just thought I'd mention that so you know that people (me) appreciate the quality and time you invest in your posts.

No, I'm not a stalker.

Thanks.

I use Digiconn ends and they work with any type of RG6 cable. At one time I did use the PPC like mike and they work great also. cybertrip I thought all SNS connectors were quad compatible am I wrong?

Nope, they sure aren't. The new connectors are color coded. Orange being RG59, Cyan being RG59 Quad, Blue being RG6, Purple being RG6 Quad, and Red being universal for all 6 Series cable.

Good deal. I never used them so I did not know. thanks
