Dear All,

Recently my SNR keeps dropping every few minutes from 7.5dB to Zero (0), and for sure this reduce our bandwidth quality and most of the time the pages cannot be displayed messages appear.

I installed another 1.8m antenna pointed at the same satellite and the same thing happens!!!!

There's a GSM tower just 100m far from my Ku antennas, I wounder if a close GSM antenna can cause such interference with a Ku Band ODU ???

If yes may i know the solution for it without for sure removing the GSM tower??!!!
