Won't this (5830-5850) C Band downlink for Eagle be the same problem
as S band? I changed all my cordless phones (4 of them) to the 5.8
ghz band so they would not crash my 2.4 ghz wireless network. Won't
my 5.8 ghz phones interfere with hearing Eagle on the 5.8 ghz band?
My Linksys 2.4 network did not bother my 2.4 ghz old phones but the
old 2.4 ghz phones brought down my network. The phones are a lot more
powerful then the network. I assume the same is the case for my new
5.8 ghz phones.
I guess for satelltes (Eagle anyway) I will just use U/V mode and
keep my phones and network the way they are. I could have used S band
down but i really doubt i will be able to use C band down (along with
all my cordless phones on the same band).
