the only way the plastic should cause a problem is if it gets ice on it. water causes attenuation. or loss of signal. usually it would only stick around for long periods if it was ice.If i cover the dish antena with plastic sheet for the birds, whether the signals from the satlite affect ?
You can buy plastic covers specifically made to cover dish antennas. I'm sure they are just ordinary plastic, so you can make your own.
