With the help of a good friend (WB2KYE), together we put the NMO in the middle of my F250 CrewCab roof. I put a Larsen 2/70 (closed coil) on there. Also ran 10-gauge Zip-wire directly from the battery to under the dahboard. Right now it's just powering the FT8800.

We took our time since neither of us did an install like this before. Prior to this it was trunk lip and mag mounts. For you who are familar with the Ford CrewCab, the hole was placed a few inches behind the dome light. There is a roof brace where the dome light is located. Actually it's in a better location. Located more in the middle of the cab roof. We used an Antenex 3/4" hole saw. Works FB. Had some burs on the inside but nothing a Dremel w/the extension couldn't handle. Had to use the Dremel anyway to take some of the interior panit off so the underside of the NMO had a good ground contact.

Great. Unless the paint was really thick, you didn't even need to scrape any off. The teeth on the NMO mount will easily make the necessary connection. Next stop, HF!

The one thing I'd wish Larsen would do, it ship the little bend wire tool to hold the center to make tightening easier. They used to send one with every mount. Folks who install these things all of the time, use the commercial version of the tool. I finally broke down and bought one.

Yes I guess the teeth could have "cut" through the paint. I feel better knowing there is a solid ground connection. My friend was holding the mount from the underside as I was carefully tightening the nut on the outside. Made sure the two holes on the center of the mount were aligned and didn't move. This way the underside tabs didn't move much and remained on bare metal.

I'm sure the FT8800 is saying... Aahhhh, that's better. A real ground plane. LOL
