Okay, so me and my sister both got TV's with inbuilt HDTV tuners in them. Unfortunately for me, the closest outdoor antenna is in my sisters room. So I have plugged an aerial splitter in, and connected both the TV's via extension cable, and the normal SD channels are working, but on the HD channels, my TV starts glitching and flashing and showing a "No signal" message for about a second every 5 seconds, as the antenna randomly gives my sisters TV priority. Do you have any solutions on how we could both enjoy the HDTV at the same time?
Also, my HD was working fine, and once we plugged my sisters TV in, mine instantly became glitchy, and is unable to find any more channels except for a crappy, glitchy 10HD, and yes the digital channels are doing the same thing. Thanks for any help you may provide 
You can try a better quality splitter, cables, or an antenna amplifier. Call your nearby electronics or home improvemnt shop for their options.
