    • Antenna input voltage question

      Hi,
      On the antanna input (the point that connected to the LNB) I got about 1.5 sec on=off voltage pulses when I measure with sensitive meter. The question is; why?

      I have a fenomen that the problem not comes from the receiver, nor from the immage, not from thesize of the antenna. The problem probably in the LNB( what I going to buy for change) but I also not understand why.
      I got on the Hotbird 8 13° E a station SF 1, horsisontally very well. 14.3 db 81%.
      There is a similar station on the 13E Hotbird 9 TSR1, TSR 2 also horisontal. On these second I not have any signal. But when I measure with sensitive meter on the Hotbirds 9 I got these pulses. I check it on an other place, other similar receiver and anything perfect.
      Thanks for any advise or explanation.
