Now that I’m getting phone, cable TV, & Internet in a pkg from my cable provider, and the tv is all digital, all 10 sets in my home require a ” set top” decoder box to use. Of course these are available exclusively from the cable company for $7.99 each. In my case $80 more monthly on top of the cost of my package! Outrageous! Is there another way to get TV signal to all those other TV’s to make them work?
