anyone know of a good way to mount a small radar to my kid's 210 outrage? also, any opinions on ban for the buck on a good radar... furuno, ratheon, sitex ???

Screw or bolt it on to something.

Hope that helps.

I'm assuming you don't have a Hardtop. If that is the case, then you need a mast of some kind to keep the emitted radiation above head level of the people in the boat. Most of the shops that fabricate hartops, towers, etc can fabricate a radar mast from aluminum. Another option would be an aluminum "arch" that spans the boat. It is also a good location to mount VHF antennnas, spotlights, or speakers. Here are some sites to look at for ideas:

If you do have a hardtop, then mounting it there is fine and Whalers provide wood laminated into the top to support and hold radar, or other antenna, mountings. For the munny, you cant beat the small Raytheon LCD radars. The digital signal processing they use will let it differentiate small targets like pot bouys where the others don't do so well with targets like that. I have one mounted on my Conquest Hardtop with pictures at:

Here is another good site with information on the installation process:

I really don't recommend mounting a radar on a 210 unless you get a T-top to put it on. For one, it won't look right otherwise and will hurt the value of the boat vs. help it.

Also, you need to ensure the radar is above all the passengers in the boat such that radiation from the radar does not beam into the passengers. There are notes on this in the radar documentation regarding long term radiation exposure.

If you do decide to go ahead and get one I recommend the JRC for cost or the Raytheon for overall best functionality. I had a Furuno on the T-top on my 1996 21 Outrage and it had a good picture under 6 miles but over that it would not work very well. I currently have a JRC on my 275 Conquest and it works great, full 16 mile visibility and better target clarity. Also much less cost.

Check out the Commercial Products Division's website at the accessories section. They show various radar mounting styles for the Guardian series from arches to top-mounts to RPS masts to console masts....

Let me know what he winds up with. I might do the same to my 210 someday. I have the T top so where it goes is a non issue.

We have a hardtop, but there's a tuna tower on top of it. So we need to put radar up above the tuna tower, when we add it?

Sheila,
Many folks with a tower above the hard top mount the radar dome on the front part of the hard top. These photos, while not the sharpest, give you the general idea. You can see the radar antenna mounted on the forward part of the hardtop on each one.

Because radar antennas emit low level microwave radiation, the radar unit should never be operated when someone is on the tower or otherwise in the path of the radiation beam. A good rule of thumb is to not use the radar when folks are on deck outside of the pilot house. I'm not a doctor, but my understanding is that microwaves are absorbed by the water in human tissue and can harm your eyes or other organs given enough exposure. On my boat, I don't operate the radar unit unless all the crew is under the T-top.

Thanks, Andy.

Radars do not emit low level radiation. Even the inexpensive ones emit 2 Kilowatts, (2000 watts) power. The pulse duration is very short, but many pulses per second are emitted, so exposure is not classified as low. OSHA has guidlines on exposure, so I'm sure there is plenty of guidelines available on line. That said, I've seen the mounting you mention with the radar at foot level. Because the beam width demension vertically is held to a farily narrow 5-10 degrees, that would keep the radiation out of the brain and eyes which are most sensitive to exposure. I wonder if it would keep your feet warm on chilly days.

I would consider a 2kW radar unit to be low level microwave radiation relative to other industrial sources. I am still very careful about limiting my exposure to it. The OSHA recommended maximum safe exposure level of exposure to microwaves is 0.2 milliwatts per centimeter squared, and the typical 2kW unit will deliver pulses higher than that near the antenna. The eyes are most vulnerable (they will overheat), so keep your head away from that thing when it's running.
