a couple of years ago i got satellite tv in the house.
they use very good RG6 so when the tech had finished making the installation, i asked him if he would be willing to make up six 15ft. cables terminated with rf plugs, with rf to gold phono adapters at each end.

for me, it was a good thing to do, price/quality wise.
