Just wondering if anyone has seen the failure I seem to have on my traditional quad lnb
I have one box with two satellite tuners and another box with one satellite tuner. The tuners are connected to 3 outputs from the quad lnb
On both boxes I have lost all the channels that are Horizontally polarised, Low. Also confirmed on all 3 tuners via the Vix signal finder facility and selecting a Hor/Lo transponder - no signal found.
Horizontal High is OK as are both Vertical Low and Vertical High which indicates that both boxes are producing both levels of control voltage and the 22kHz tone where required.
12.5V to 14.5V with no tone = vertical polarisation low band
12.5V to 14.5V with tone = vertical polarisation high band
15.5V to 18V with no tone = horizontal polarisation low band - all channels missing
15.5V to 18V with tone = horizontal polarisation high band
