[BC] chain link fence effect on satellite dish?

[Kevin C. Kidd CSRE/AMD]

Not at all stupid.

I have fixed 2 specific interference problems by under-illuminating a
large dish.  Since the effective size of the dish was reduced the signal
dropped slightly but signal strength wasn't the problem.

Another problem that I discovered during these interference chasing
ventures, was that regular old home type changeable polarity feeds are
severely lacking in polarity selectivity.  Changing to a fixed polarity
feed has cured several intermittent adjacent sat interference problems.

Later,
