I picked up a 22khz switch to use with my DSS dishes, one pointing at 101, the other at 119. I've already sent one back because I thought it defective. I got another one. The problem is that on the 119 bird, without the switch I'm getting a 78 signal, with it I get a 40. On the 101 the signal only drops from 96 to 91. Is this normal with these switches? Do I need some sort of amplifier? Any Help Appreciated.
