I've got a TCL digital STB and want to tune in a second TV. I've connected the STB to the second TV via a length of coax from the STB's RF out. When I tested using a short stretch of cable (1m) it's fine, but the second TV is probably 7-8 metres away and when I connect it up with a longer bit of coax, the signal dies and I can't receive anything.
What chance do I have of getting this working? Will special cable help? Is there a practical way to boost the signal? Will splitting the cable before it hits the STB help?
For added difficulty, the second TV is old and only has RF in.
Thanks
