Before I last decorated I ran some RF cable from our Sky box to a 2nd TV upstairs which worked great for bedroom viewing. 6 years later... I'd like to re-use the RF cable run to feed from a quad LNB into a Freesat box upstairs so we'd have Sky downstairs and Freesat upstairs. (Can't quite warrant +£10/month for Sky multiroom). My question is will the RF cable be up to the job of carrying the satellite feed about 20 meters up to the receiver? Thanks.
