Hi everyone, I know this is going to be a silly question but I have to ask it.

Should my Avtex 153D TV and my Multimo portable sat dish be able to talk to each other and provide me with digital free to air channels? OR do I need a receiver to fit between the two. I thought the former and have done a little fiddling about but with no success at all. Not a glimmer. I've had this nagging doubt that I need something else.
Thanks
Vick
