I have a 10.5ft cband dish that I am currently using to get from 139w to 43e I also have two 10ft dishes that are just collecting dust, what I wanna know is, is it potable to make the 10.5' dish bigger using the two 10ft dishes I have and what are the complications to a project of this size and what would one need to know? Thanks for all responses.:D

You can add gain to a dish adding custom panel work, I've done it in the past & got quite crude panels to add gain / improve SNR & at Ku band with fixed lnbF too.. easier on C Band.

The focal length of the other dishes might be a bit out, I think the best way is to test them live and see if you can get a position for them that gives appreciable gain and work from there plus be mindful that the optimum position for the feedhorn and even the focus may alter. Sometimes it can be more down to increased shielding.

Not in love with butchering dishes though.
