2019 Ford Police Interceptor roof mounts

[Brian338]

Posted already in Intro.My bad.Not sure what kind of mounts these are.Nobody seems to know.I have nmo mounts and rain caps as option 1.Option 2 black rubber caps.I'm assuming these roof mounts I have are installed from inside.

That just looks like a washer with rtv attaching it to the roof, you will have to remove it to see if there is a 3/8” or 3/4” hole under it. NMO’s with rain caps would obviously be the best hole plug.

Threaded is a antenna mount. There is probably coax cable run under somewhere under the headliner. The others, like already mentioned are washers stuck into RTV sealant. There might be a very large hole under that if they had to cover it with a fender washer.

I have the holes from when I removed my roof rack filled with white RTV sealant. Been that way for years without leaking.

I didn't even think of it just being a washer.Makes sense though!Thanks.

Thanks!

If it's just a washer I might not have to drop the headliner inside.That would save some time!

If it's just a hole I can clean it up and install NMO with rain cap.I hope!Nothing is ever that easy!

If it's just a hole I might get away with cleaning it up and installing NMO mounts with rain cap.Nothing is ever that easy!LOL.Won't have to drop headliner.

Now I know when I asked the the supplier of my NMO mounts what the heck I had on my roof,they replied, they had never seen anything like that before.Freakin washer.How did I not think of that!Duh!!!

I agree, it would be odd if it was that easy. I do have rubber plugs if you go that route, as well as NMO"s and rain caps, it the holes are larger, then you need to be more creative.

I would agree with BKennedy that there's likely a large hole under the RTV/washer. The previous mounts were likely ripped out of the roof, and the remaining one doesn't look too good either
If you can clean off the RTV and flatten the bent metal, installing a new NMO mount with a rain cap would be the best repair. Otherwise have a bodyshop fix it professionally.
I'm guessing your PIU may be a slicktop, as a light bar usually protects antennas behind it.

Maybe consider covering with a "fake" antenna as there are many versions out there.

They are the Motorola-style NMO type mount. They were installed from the outside. It seems that someone installed a 3/8 inch hole for the antenna and elected to install the smaller antenna and apply some glue to seal the washer over the hole. When the antenna mounts are properly installed correctly, they don't leak. However, that said, if the glue is securely holding the washer in place, you can either obtain a antenna hole plug for the 3/4 or 3/8 inch hole; or, as stated, use a cap which will screw over the top of the mount.
