Could anyone who understands the link equation please comment on the following regarding dish size for Astra 28.2E:
In Israel on a ChannelMaster 1.2m offset dish with an Invacom C120 mount LNB fitted to a ChannelMaster Offset feed I have measured (using a Satlook Digital NIT) a carrier to noise ratio (C/N) of 4.6dB on 11.973V
What should I get using the same LNB on a Prime focus feed on a 3.6m prime focus dish?
The reason I ask is that the figure I have measured on the 3.6m dish is a C/N ratio of 9.0dB.
The 3.6m dish was an old DH 2 piece dish that was missing its correct joining strip and I suspect that its performance is compromised.
Should I be getting something nearer to a C/N of 14dB?
