24 GHz feed for my EME system

Designed for a F/D = 0.4

Main principle: a transition from recktangular to round waveguide and a choke to equalize the E and H pattern.

The choke is made of a small part which is soldered to the main part.

It works well for my EME system, its also in use for my tropo system

 Drawing of the feed

 After the parts have been prepared they are soldered together.

 The different parts must be slightly bent outside to fit into each other.

 Take a look at the pictures to see my final result.
