Possibly, but it won't look like that one.

If you are looking for efficiency you should go for a transition that is a minimum of 3" long, with tuning stubs inside. I would usually fit an orthomode with one port capped off.

What are your lower/upper frequency requirements ?

10.7 to 12.75
Have a rummage when you get a minute
 
This Cahors offset feedhorn with adapter to WR 75 looks interesting....I guess it is feedhorn with C120 flange + adapter C120 to WR 75. My guess only - comparing feedhorns from pictures.

Interesting, thank you.
 
John,

I have this OMT from an old VSat dish if it helps. Note ports marked RX TX

Thanks for the offer Joolz, unfortunately an OMT due to it's physical shape cannot be used in my next little project as it would be rotating and collide with the motor and positioning drive that sits along side it but thanks anyway.

The transmit will always be inline with the feed. A higher frequency means more loss if it has to go through any transition plane.
