Does anyone know what kinda gains can someone expect going from 1m to 1.25 or even 1.5m?
What a wonderfully helpful reply, well done:clapping:compare surface area
Im thinking of getting a bigger dish for feeds cause currently it's a hit or miss with some of them.@meho7 Can you specify what do you mean by "gain"? How can you measure and compare gain?
I agree with @dmr0x.... if you compare surface area of aperture than surface area of 1.5m antenna is ~55% bigger than surface of 1m antenna, and 1,2m antenna somewhere in the middle.
And, depending on what you mean by "gain" I would say that gain of 1,2m antenna system better than gain of 1m antenna system. Gain of 1,5m antenna system is much better.
