I came across this info related to dish size, power vs signal bandwidth by M0DTS.
See here for an interesting table:

Dish size vs power vs bandwidth
Re: Dish size vs power vs bandwidth
Rob M0DTS has prepared an easy-to-read table that shows the trade-offs between three variables:
* size of dish antenna
* RF bandwidth of your signal
* output RF Power you will require

Re: Dish size vs power vs bandwidth
Hi,
It is indeed specified to make 53dbW eirp power.
So that is 100W into 2.4m dish.
But is that cw signal? of modulated signal?
The 3 user channels are 1.8Mhz wide (=1500Ksym)
So what would be my PA power (measured in cw) like?
knowing that i can only use 1/4th of the power for dvb-s
73's
