Hi
Just had terrestrial aerial fitted in loft space. Unfortunately, I wasn't about when it was put in so unsure of make/type and whether or not a booster was added to circuit. TV loops in master bedroom (2nd floor) straight into Panasonic TV with internal freeview, no problems (although not all HD channels being found on most recent scan).
However, Humax HDR FOX T2 (1st floor) connected to Panasonic HD ready telly is breaking up on the HD channels. I've read around the forums and thought maybe it was signal strength (seems to be around 100% strength to 60% quality on each mux) but am baffled about why SD would be fine and HD breaking up/pixellating so badly. If I try an attenuator to bump down the strength on the HD mux, am I risking losing the SD mux?
FYI, we're 44km from Crystal Palace (in Ware, Herts), and I've done both manual and automatic tuning.
Cheerio
