RE: Loftbox problem....

["Paul Gordon" <paul_gordon@xxxxxxx>]

Aha! - a case of RTFM I see... ;)

OK, so that clarifies that one of my earlier assumptions was incorrect,
that
being that the loftbox would internally connect the inputs from "TV
Ant" and
"FM Ant" to the room outputs all the time...

Obviously then only the signal that is present at the UHF2 input (and
*only*
that signal) is routed to the outputs, which obviously narrows down the
troubleshooting process a bit... however, the problem then is, that AFAIK,
I
_have_ routed back via the digibox RF2 output - MWSP - loftbox UHF2 input
as
described in the manual...

I'll spend a bit more time double-checking what signal is coming back from
the MSWP via the UHF2 cable, but I'm 90% sure I did it exactly as per the
manual...
