Default How high to mount Radar - Can the arch support it?

I picked up the Lowrance 3g radar and am trying to figure out how to mount it on the aft pointing radar arch of my express cruiser. My Bimini cover snaps into the forward edge of the radar arch and the frame actual rises 12 inches just in front of the the arch, so that if I mount the radar at arch level there will be a horizontal pole right in front of it. To clear the pole I would have to mount the radar 16-24 inches high. Most of the radar mounts I have seen are angled aft. I may be overthinking this, but I am a little concerned that the stress on the radar arch which is about 40 pounds, but is likely more given the lever effect of the aft angled mount, may be more than the arch can handle. That being said, the arch seems very strong to me.

How high should I mount the radar, and can the fiberglass arch handle it?

Check their site. Bottom line is you dont want the beam hitting people or metal

Isn't it supposed to be a "radar arch"?

I suggest asking the manufacturer of the radar if the bimini frame will be a problem and I suggest asking the manufacturer of the boat if the weight of the radar will be a problem.

If you can use a substantial backing plate for the radar mount, it will spread the load and the weight will be less of a concern.

BTW: My slip neighbor has shown me several pictures of half naked women hanging upside down from his boat's radar arch.

The 3G is safe to mount right next to your head.

The 3G dome only weighs 16.3 lbs.

Can't imagine the arch won't hold it.

A photo or two would help us help you.

I need to stop shooting from the hip. ( out dated and wrong again.)

Guess I will have a drink it's after 10 am

I think a mount is advisable. Not because of radiation as the 3G radar is safe, but because of the SS bows in your top. It would be best to get the radar up above them. Here is a mount that would work - http://www.boemarine.com/Seaview_10A...on-PMA-10G-7L/

Unless your arch is very flimsy, this won't put to much stress on it.

Edson pedestal is what I use with my 3G on an aluminum arch...a little cheaper perhaps. I just got the 6" one. Your specific geometry and interferences dictate.

Tilt it down a hair in front- so when you're on plane you aren't shooting radar into the sky.......had a buddy have this issue with his Lowrance broadband radar.

He didn't give me the pictures, he just showed them to me.

Here's a sample from his facebook page:

"half naked" would imply either a missing upper or lower bikini part. "hanging from" means holding on to while not standing on something. while either of the two gals would be great canidates, neither fit the defination of the statement.

I'm going to have to work on my communication skills because I'm just not getting anything across this evening.

He showed me pictures of half naked (topless) women hanging from his radar arch but he did not post them on his facebook page, nor would I be able to post them here if I had them, which I don't.

I hope this is clear.

Im gonna give you a pass on the challenge. I think after seeing the picture you posted, I have seen enough evidence to believe it could be true. Good Work!
