What’s the roof made of, and why on earth would you need a 2” hole for a dome?

5" aft leaning riser. Look at seaview website. You can get an anchor light riser for them as well and 2 wires is all you have penetrating the roof. They come with a rain boot, but use marine silicone where wires penetrate roof.

If you ever plan to put a raft in a canister up there, go with the 10" riser instrad

That's the same mount I use, height under bridges is a minimal add and the bracket lets the radar work well.

I went the cheapo route. Mounted directly to the top with about 1" of plastic refrigerator washers on the back 2 bolts between the top and radar to give it the forward rake required

Definitely don’t need a 2” hole!

I’ve had a similar set up for about 10 years. Absolutely love it and RADAR performance is excellent......

You could always cut and reterminate the cable too. They just advise it to stay full length when possible.

Definitely elevate it, might need a bit of pitch as well, depends on the attitude at different running speeds. Elevating the radar will help get the beam over your rocket launcher aft and the bow rail forward as well as clearance over your skull. I mounted mine with a 5" aft raked Sea View with a stern light on my 23 Steiger. Hole for the Garmin plug was 1 1/4", no need for a 2" hole. The hard top on your parker is plywood cored, drill your hole and then seal the raw edge with epoxy before running the cables and attaching the mount

Different brand of boat but some good info in this thread when I asked the same question as yourself. The process should be identical for your Parker

Adding radar to hard top

huh? it is a standard cat 5 cable & connector w/crossover pinout carrying low level digital data signals. all analog RF signals are in the unit itself. very easy to cut & crimp a new connector on. best to do it on the 'display' end to leave the factory connector intact on the radar end which will be more weatherproof.

Agree with Chainsaw. Get yourself a RJ-45 terminating kit and it's a breeze. The only trick is getting the cable lined up correctly in the jack before crimping. You definitely want your radar up and angled unless you never get on plane.

The mounts above are very nice but I've always wondered why you don't you get a blind spot having the bracket higher than the dome and so close? Is it too close to interfere? I went with a Scanstrut tower for my install and my dome is higher than everything except my downriggers when they are in the "way up" position.

I went with the Scanstrut composite because I heard that the 18xHD was loud and I felt that a metal one would transmit the sound into the PH would be less. Like I said I absolutely love the mount but don't like the light off to the side. Most people don't even notice but I do. Fireisland1 that one you made is awesome, you have some talent there! I actually didn't have to drill any extra holes all of the cables went through the existing anchor light hole. AS I have posted in previous threads, my radar improved greatly with a 4 degree wedge.
