Build an Arch
We have a friend who built an aluminum arch on the stern of their 376 and they are so glad that they did so. They have now hung a wind generator, radar, hailer, and additional VHF antennae on it plus dinghy davits. I personally would not go with the davits because a hanging dinghy would get in the way of the fishing. If you want, I could put you into touch with them. Toucan Dream

Another Radar Mount Option
For my V32, I went with an Edson system of base, pole, transmitter mount and accessory antenna mounts. Ordered the whole system through West Marine for about $350. Top quality. Hung a second VHF antenna, loran and cell antennas from it. Had a local machine shop make up a SS 90 degree mounting bracket for the transom for about $60. Total installation was real sanitary. (I was going to consider an arch, but after dealing with two fabrication shops, I was convinced I was better off with a factory-engineered kit) Good Luck, RD

Garhauer
Try calling Garhauer. They have a real nice pole which is very sturdy and comes with a hoist for lifting your outboard. They are very helpful and Practical Sailor rates their tower as a best buy. No. is 906.985.9993. Good luck, Dan Arsenault Serendipity Too

How High?
I too am in process of mounting a JRC 1000 radar. I favour stern mount as the mast conduit looks almost impossible to find. I have a design for a Stainless arch on the aft rail but, to shoot the beam over the top of the boom when it is topped up makes the arch too high for comfort. Aiming it below the boom when the sail is up means the crew heads are directly in the firing line. I have looked at our (UK) National Radiological Board website regarding "non ionising radiations" and this indicates the levels of radiation will not be dangerous from the point of view of microwave heating on the brain. What they do NOT deal with is the instantaneous effect of the peak power on the brain cells - brain being an electrochemical device and all. Of course all the power boats have their scanners directly behind their fly bridges but I have yet to meet an owner who is not brain damaged already. Anyone got and real medical evidence please?

Eye damage
I do not know about brain injury from radar transmissions but I know from personal experience that it can affect color perception. My eyes were damaged while working on radar guided missiles when I served in the air force. I am not sure of the differences in power levels but the operating frequencies are close. I think the power levels I was working with were much lower than the power of the scanner of your radar. I would not put a radar scanner in a possible line with anyones vision. In addition to this problem, the range of the radar will be severely limited by the height of the scanner on a stern pole. Mine is mounted on a simple bracket I made which clamps onto the spinnaker car extrusion on the mast and the cable is lead down one of the shrouds to the deck. This setup is easy to put up and take down if I choose to do so.

Radar Brain Damage
I read the discourse on the possibility of altering color perception due to excessive absorbtion of radar energy. I spent 20 years in the Air Force working with Air Traffic Control Radar. Most of the time was spent inside a trailer working on two radar systems of differing power levels and operating frequencies. I am not positive about brain damage (after all I spent twenty years in the AF) but I am sure there was no change/damage to my color perception. I would suggest you use a radar pole on the stern rail tall enough to put the radar dome above your head level under normal operating circumstances. The radar will cover all area out to the horizon as perceived at the radar antenna level. Mounting the radom on the mast will give several miles extended coverage but since you will not be trying to avoid mach one jets, ten+ miles coverage will give you a reasonable margin of safety in most all circumstances. Enjoy your new toy.
