Gordon,
Our display-to-scanner cable drops down about 18" before heading aft
through a hole in a cabinet. This plus a little slack in the cable
makes it so the cable is not unduly flexed or stressed when the arm is
swung in or out.

Hope this helps - Dan

Exactly. Would love to see pictures and how you routed the power and
other cables to (presumably) the nav station/DC panel.

I'm in the process of installing a JRC 2000 radar on my boat. The first
thing I did was install the display. I wanted to be able to see it/operate
it without going below. I'm using 2 horizontal RAM mount arms attached to
one of there vertical mount bases. This is bolted to a small cabinet on the
inside of the bulkhead. I can swing the display out so that I can see it
from the wheel but I don't think I'll be able to see fine detail (don't know
for sure as not fully operational yet). In this position the display blocks
access to below. I can, however swing it to the side so that I can go
forward to look at it and also go below easily. The cables are an issue
I've been wrestling with. The power and NMEA cables are not really a
problem as they are small diameter flexible wire. Easy to route. Its the
display-to-scanner cable that is the problem. Big cable and not that
flexible. I think I may have to disconnect it each time I swing the display
into its storage position inside the boat, against the cabinet. To route
this cable to the stern I'm thinking I will have to glue some white 1"
diameter water pipe to the overhead in the 1/4 berth and feed the cable
through that as I cannot get above the head liner and I need some play in
the cable. When not in use I will have a bracket on the cabinet where I can
store the cable. It will work but its not going to be as neat as I would
like.

Thanks Dan
If I have enough slack in my cable I may be able to work out something
similar. I was thinking if I made a coil or two and connected them with
small shock cord it would act somewhat like a spring as I swung the display
back and forth. I would probably need to suffer the expense of buying a 15m
cable to achieve this and then I'd have a 10m cable that would be difficult
to sell. Should know in a few weeks as I'm finally getting my radar pole
together.

Ours is the Garhour pole with the outboard hoist and we are extremely
happy with it.

Thanks for the descriptions. I always learn something when I ask stuff
like this, because we are forced by technology to rethink this stuff
every few years...even though a lot of the boats are still made for
'70s and '80s considerations...

I'm building my own.
I found a 10 foot length of 2 1/2" diameter aluminum tube in a scrap yard
for $10. They sell scrap aluminum for $1 per pound. A new length would
have cost me $100 from a chandler plus shipping. 2 1/2 inch is not that
easy to find. I could have easily used 2 inch but a friend recommended 2
1/2 as he thought there would be less vibration.
Garhauer makes nice stainless support brackets for 2 or 2 1/2 inch pipe,
only $29 I think. I bought three of these and scrounged up some 1" OD
stainless tubing for arms. To connect the arms to the brackets on the pole
and stern railing I'm going to use the end caps they put on tubing for
dodgers. Just going to bolt the ends caps together.
Got to get a platform welded on the pole. I was originally going to buy a
Waltz RLS but discovered they had gone out of business. Questus was just
too much money for me so I was just about to order a Garhauer pole when I
came across a Waltz platform on eBay for $300. I'm going to bolt this onto
my welded-on platform. I should end up with a self levelling radar pole for
about $500US.

How about PVC pipe or the like?

Uh-oh... Not all aluminum is created equal. I hope what you bought is
suitable
for a marine environment.

Waltz is back in business with a new owner. You might be able to buy
the parts to complete the backstay installation combined with what you
bought on ebay. There are also good deals on the Questus if you search
long enough.

That would be even worse for this application. You are mounting a 20
pound weight on top of a 10 foot pole. That pole is mounted on a boat
that will be pitching, rolling and yawing every second it is in the
water. My advice is that this would be a good place to spend the
required, though painful, bucks to do things right.
