Hi I've just bought a new HD LED TV and a Twin Tuner.
I first plugged the TV in to see how it worked on its own but could only get a few channel after following all the instructions on how to do the scan. The few I got were Pixelated and lost sound, while others just had a blue screen
I then put the antenna cable into the Tuner and Connected the HDMI cable to it and the TV. I've tried to scan for channels and I only get SBS and Radio.
Once I got Eleven and ONE as well but the picture was awful and was bad sound quality. I got all the channels on my old TV with the Top box I had and The TV in the lounge gets them all too. Just wondering what the problem might be?.

Where is your external antenna located ?

Thanks for coming back and letting us know. Welcome to AMHD.

Glad better coax did the trick, If you want Better, An antenna Preamp would do wonders.
The higher the frequency the greater the loss is in Coax. Twinlead(flatwire/balanced)has less loss than coax.
