Thanks for the clarifications, guys. So, to sum up, if you have a
mizzen, it's a great spot for a radar with little downside unless you
think you need the height of the mainmast, but then you may foul an
overlapping genoa.

Does that sum it up?

Just remember that a radar sends out radio waves, and any metal in front
of it will cause part of your radar signal to be bounced back to your
radar. The metal mast and rigging may not obscure your radar display
(an empty "shadow area"), but some of that energy will be bounced right
back and can either cause interference or even damage to your radar's
receiver. All the more reason not to use a 4 kw system.

Admittedly, any installation an a sailboat would be a compromise, just
as long as you're aware of whatever the limitations/consequences might be.


Now, if I can just figure out how to put a windvane AND davits behind
a mizzen mast....G


The windvane should go high on the mizzen, as on my friends boat:

Note that the davits are behind, and also serve as a good place for
solar panels.

Wind -vane- or wind -generator-? The pictures show what I'd call a
"wind generator". Mounting a wind vane self steering system is a whole
different kind of animal. Which is it you need help with?
