How to use Ideal 92-650 F connectors on RG-6 quad shield cable?
First to be clear you want to strip and fold back correctly.  Regular RG6 has these layers from the inside out:  

center conductor 
dielectric 
foam 
foil 
braid 
jacket


Quad shield RG6 has an additional foil and an additional braid, so it's like this from the inside out:  

center conductor 
dielectric 
foam 
inner foil 
inner braid 
outer foil 
outer braid 
jacket


So there's more material to fold back, and if it doesn't get folded back out of the way, you're going to get hung up inserting the connector.  

When you strip the cable, you want to strip back 1/4" from the tip all the way to the center conductor, and another 1/4" of the jacket.  Then you fold back the outer braid, tear off the outer foil, fold back the inner braid, leave the inner foil on the dielectric.  

If you fold everything back, and nothing gets tangled while inserting the connector, it should go in just a little tighter than regular RG6.
