I have made LNB cooling test.
I use older Sharp LNB without plastic cover. Satelite 19,2 ASTRA, offset dish, multifocus, signal adjusted exactly above erros. LNB temperature before test 22 degree C. Receiver Dreambox DM 800 HD show S/N 10,6 dB. I use cooling spray with declared temeperature -55 C. I do not know exact temperature because my easy IR termometer do not measure it.
LNB was frostliness for some minute then recever show S/N 11,0 dB. Level was stabile for some time.
Nothing dramatic, small change.
Looks for nothink.
