I'm looking to run video from my Receiver in the wall to my tv hanging 35 feet away. Due to vaulted ceilings and wall runs I think I need 70 feet total but I don't want to short it.
while I have run 50' in a single cable with no issues, I'm not sure about running 100' strait cable, even if it says it's got an inline booster (eg this or this). Should I use something like that or a HDMI Extender / booster?
Also, if I use a booster does it have to go in the middle of two shorter cables or can I put it on either end?
The eventual media will be HD cable tv, Xbox, blu ray, and wii all switched and controlled from the home theater receiver, and output via A single hdmi run to the tv.
For 80ft, I think you have to use 24AWG to get reliable transmission.
The second link you provided is for a 24AWG, but the seller has low stars.
You can either get just a 24AWG cable with an HDMI Extender or
a balun, HDMI over CAT extender
Concur that at that length you should be looking at a balun solution. Suggest you look into an HDBaseT product. Monoprice has one for <$200. Only needs 1 Cat5e cable. But if this is new construction (not a retrofit), I would recommend you run 2-3 Cat5e/Cat6 to a new projector location anyway, as well as a flex conduit for "the future".
