Best feedhorn for 10 foot parabolic dish?

rufusputnam · 09-08-2005

Hi -

Any antenna experts who can tell me the best feedhorn to use for a 10 foot dish?

Is the aperature width of a bi-quad (like the one typically used on the PrimeStar-type dishes) big enough to make optimal usage of the increased surface area of a 10-foot dish?

I've used a cantenna and an omni at the focal point, with good results, but I want to know if there is a feedhorn that is theoretically optimal.

Thanks,

Rufus

The gain is so high on a dish of that size that it is illegal, unless you're a Ham.
