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 Gordon Wedman wrote: "rhys" wrote in message ...

When both are deployed so the helmsman can see them, it's a little inconvienient since to in or out of the hatch, you have to either carefully step over them or swing one of them out of the way. In reality, this is not a big deal since the radar is only rarely used (but when we do use it, we are REALLY glad we have it). Exactly. Would love to see pictures and how you routed the power and other cables to (presumably) the nav station/DC panel. R. 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. "Dan Best" wrote in message ...

Pardon the interruption, but what are you doing for a radar pole?

Ours is the Garhour pole with the outboard hoist and we are extremely
happy with it. Fair winds - Dan Gordon wrote: Pardon the interruption, but what are you doing for a radar pole? Gordon |

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...

"Gordon" wrote in message ... Pardon the interruption, but what are you doing for a radar pole? Gordon 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?
