Now that sounds a bit more do-able, and it shouldn't be too much
of a problem for average technically minded homebrew operator to
put together a system capable of delivering that power level
on that band, and if the level were increased, a dish with a
bit smaller radius but deeper parabola might obtaing a tighter
focused signal - with let's say about 5-10 watts.

No WAY! am I going to use tubes !!! :)  Are you saying that
a PEP of 10 watts on 4 GHz can't be done with 'solid state' ?!
Charlie...  I'm on the "TVRO" echo and other BUD message areas
because I'm intrested in the use of LARGE DISH C-BAND systems,
not in the hype behind the DBS/DSS market.  I'm sure those have
their place with those that are in a limited space and need a
small unobtrusive array, but I consider C-Band "alive and well"
and prefer to base my actions/plans on furtherance of THAT band.
So, while I appreciate your comments and you have provided some
valuable information, when replying (if you ever do after this
comment :) to me, please limit your references to BUD systems.
Thanks a bunch...
