Simple feed horn for parabolic dish on 6 and 3 cm
bands
I am told that you don't need to solder the round plate to the
end of waveguide, it works just as well by gluing it.
For 23/13/6cm I use DL7QY broadband feed (1.3-10GHz), but the
problem with such broadband feedhorns is
that the optimum focal point is different on the different bands,
so you may be better off with some different feedhorns
for some of the bands.
