Picked up a JRC 1800CP off Ebay for Cruis'n Rulz! I got this wild-ass
idea-always wanted an open array scanner; I think they look way cooler
than a radome. However, O/A scanners are much heavier than the Radar
Arch will safely handle in rough seas.So...
Having had the box open for 30 minutes, I promptly voided the warranty
by completely dissassembling the radome. Did some evaluation; My plan
will work. A little re-engineering, some glass work and metal fab, and I
will have a 24" 2KW Open Array (looking) scanner Atop Cruis'n Rulz!. I
can reduce the weight and size of the resulting assembly by about 50%
from the radomes original weight of 11 lbs., and reduce the footprint to
a 5" square. The cable will exit underneath directly into the Arch,
instead of plugging into the back. The resulting size of the
re-engineered drive/electronics package under the antenna will be about
6"X 9" and 4" high. Final weight about 5-6 lbs.
Stay tuned for pics on my website.

It's the part about voiding the warranty that scares me.

What is an open array scanner?

I'm familiar with electronically steered phased array antennas and the
traditional fixed phase array antennas which use mechanical rotation to
sweep the radar beam but I have never heard of an open array scanner.

Could be an example of a commonly used, commonly understood term that
is not technically correct.

An "open array" radar is a term often used to describe a radar where
the antenna rotates in the open air, rather than under a dome.

Open array simply meaning 'Not Enclosed', or 'Not in a Radome'.
