I know this has been hashed and re-hashed and I've read too much, now I'm confused.
My setup is in a camper which has a living room, front bedroom and back bedroom. Believe it or not, there are three tv's in the camper. Cable recpetion is excellent on all TVs with the cable modem unplugged. I have a splitter, brand new, but a cheapy with no specs on it, that splits off of one of the tv connectors to the cable modem. The rest of the wiring is inaccesable other than a cable jack in each room.
Cable modem works great for internet access when plugged in to cable but my tv recption gets wrecked. I get noise on channels 2-7 and channels 52-60 are virtually wiped out by snow and are unwatchable.
I'm thinking that I should split the wire where the cable comes into the camper running one wire to the cable in jack that feeds the the tvs with a 50mhz highpass filter and then another cable going to the cable modem all by itself. Does this sound like a reasonable approach or are there other things to consider ?
Any help would be appreciated.
