Note: My earlier recommendations (4kw, stern mounting, etc.), take into
account you have a racing boat, are around other racing boats, and if
your are really compelled to add a radar at all, focus on features that
will make it worth doing and features that are more important in
minimizing the impact on racing ( than the weight of the radome ) in
planning your total purchase and installation, rather than for example
range. Even if you could save 5 pounds off the typical 18 lb weight of
a radome, it wouldn't necessarily improve performance since the weight
of the entire system (assuming no additional batteries are needed) will
be north of 50 lbs, and the 5 lbs especially won't matter as your deck
crew is dealing with a halyard or sail getting caught in it even for a
few seconds.
