This is what your state (all I'm stating is they won't work 1:1):
It's 1:1. A 2.4m offset should have a similar gain to a 2.4m prime focus.
Is this your post? or am I altering your original post?
IF you Claim that a 2.4 off set fed antenna operates 1:1
compared to a 2.4m prime focus.
post definitive proof that they indeed operate 1:1
so I can send to all antenna manufacturers (I know) and tell them to stop their production line on off set fed antennas.....and start manufacturing only prime focus.
That there is no need for that design (off set fed) and it was a mistake in the first place.
Books (theory) and Manufacturers can't be wrong!!!
Mr. Paul Wade has published tests...actual tests and I quote from his tests:
Summary
An small off set parabolic dish can deliver more performance than a conventional dish of the same size.

Mr. Paul Wade (
w1ghz@arrl.net) : tell him to take off from his web site this chapter and that prime focus perform 1: 1 compared to off set fed antennas as you state here on Satelliteguys.com
Please send your deep explanation that Off set fed antenna performs as good as prime focus, so he throws away all the research he has dedicated to off set fed antennas and how they perform, what should be the correct feed (conical, scalar, etc.) all was a waste of time.
post a copy here so I can send also to other publishers that have entire chapters dedicated to off set fed design.
That link I found on Wikipedia

who also has a page to give concepts and links.....
after all of them agree I will agree....
If you're wrong will you agree????
I have stated that prime focus is cheapper (no doubt about that) but I think it's bad for any kind of forum to post inaccurate information, this is the reason why I keep posting on this, some readers might get the impression they wasted their money on off set antennas and that they should have bought a prime focus (much cheapper) the reality is that off set fed antennas are more efficient than regular prime focus........
