Update: I have finished running the RG11 through the conduit and under the house and it’s all hooked up to my home television. I have 150’ of RV11 connected to 10-15’ of RG6. (It’s was already hooked up through the floor and to the tv so I figured I’d see how it works.) I have all of my channels now!
I did learn something, though. I should have listened to jimmarako and put wire pulling lube in the conduit. It was incredibly difficult to pull. But on the brighter side, I only had to cut the existing conduit in one place. Oh, I also learned how to cut conduit without cutting the expensive wire already in it. Slide the next size conduit smaller inside and then use a cut-off tool on a dremel. It scars the inner conduit and not the wire.
