Marine Sanitation Professionals Discuss How to Install a Radar Dome
Your Marine Sanitation Specialists Share Tips on Installing Your Next Radar Dome
Raritan Engineering your marine sanitation suppliers would like to share with you these topics we thought would be of interest to you this month regarding how to install a radar dome.
Your marine sanitation manufacturers talk about how proper installation plays a big role in maximizing the performance of marine radar domes. So, if you’re considering installing a new solid-state dome radar aboard your boat or checking out the install aboard a boat you are buying, keep these factors in mind.
Elevation
To perform effectively, mount the radar dome high enough to give it an unfettered, level and full-circle view of the horizon, but not so high as to be adversely affected by the boat’s pitching and rolling. The most common way of achieving this elevation on center console, express cruiser and walk around cuddy models is to install the dome on a hardtop or T-top.
Forward Angle
The radar should be installed so that it’s level while the boat is underway. The bow angle is often greater when the boat is running at speed than when it’s at rest. So, if you mount the dome level with the boat at rest, the radar beam will be aimed upward while underway.
Beam Clearance
Today’s solid-state marine radars are so sensitive, they can detect objects that are just an arm’s length away, including onboard elements such as the outer edges of your hardtop.
Other Antennas
Avoid mounting your new dome radar on the same horizontal plane as a second radar scanner, as the two radars systems can interfere with each other; a conventional-type magnetron radar can actually damage a solid-state scanner in this configuration.

I decided on the Furuno, I compared prices, and I ordered the thing. I didn’t think to specify the length of the monitor/radome connector cable. I noted that it came standard with a ten-meter cable. Super!
In San Diego, I hired a rigger to rivet the radome mount on the front of our mast, about nine meters up. I didn’t give the cable length a second thought during the two hours I spent trying to fish the cable past obstructions on the mast interior and then out through the tiny hole at the base. But I’m no dummy, less than five minutes after completing that job, I realized my mistake.
“No way. Under the plastic sheathing is metal mesh sheathing, ten insulated copper wires, and a coaxial cable. If you splice in unprotected wire and coax, you’ll get too much interference, it won’t work.”
So I had a plan and with the help of my friend Dr. Stewart in Eureka, I tracked down the cable, terminal strip, and junction box I needed. In a day I finished the installation of the radar I’d bought three months before—and it works like a charm.
It was a hassle to take the do-it-yourself approach, but I spent less, I know much more than I would have had I hired out the installation, and if we ever decide to pull the mast, it will take me about five minutes to disconnect the radar cable. Bonus.
Sheriff's dive team testing sonar finds car of man who went missing 41 years ago
A Goodhue County sheriff’s office dive team was testing its new sonar unit on the Mississippi River when they found the vehicle of a man who went missing in 1976.
The vehicle belonged to David Jorgensen, who was last seen on February 27, 1976 on Trenton Island. In early May 1976, Jorgensen’s body was located on the Wisconsin side of the Mississippi River in an area known as Warrentown.
At the time of the sonar discovery, the water level was high with strong currents and it was too dangerous to send the divers down. Thursday, a dive team was able to place straps on the vehicle and make a successful recovery.
Jorgensen’s family members and friends gathered as the vehicle was removed. The sheriff’s office hopes this recovery will bring closure to the question of what happened to Jorgensen’s car.
The Pierce County Sheriff's Office, Minnesota State Patrol, Minnesota DNR, Red Wing Fire Department and Siewert's Towing and Recovery assisted with the recovery.
Don't forget these amazing tips for installing a radar dome. 1) To perform effectively, mount the radar dome high enough to give it an unfettered, level and full-circle view of the horizon; 2) The radar should be installed so that it’s level while the boat is underway; and 3) Avoid mounting your new dome radar on the same horizontal plane as a second radar scanner.
