Occasionally I take a tv outside to a screened in porch. I have a cable run through my attic from my den that allows me to keep my receiver in the den. I used to have a 612 in the den and I installed a 10' piece of coax on the antenna input on the back of the 612 and it allowed the remote to work great from the porch. But the Joey that I have there now does not seem to have an antenna input. I can sit the Joey on top of the entertainment center in the den and I can get the remote to work somewhat. But it's not great. I keep having to wave the remote around trying to find the sweet spot. Any suggestions? Why would they have an antenna input on the hopper but not the Joey?
