FYI, I purchased the Rail Ratchet VHF Antenna Mount (Item: IF-010535) from Cabelas hoping this was the Shakespeare model. It looks exactly like the Shakespeare Style 4190 Rail Antenna Mount, but not sure if it is. It comes in a plain white box with no markings or paperwork from Shakespeare. Anyways, the specs say it fits 7/8" railings, but when trying to mount to my center console grab rail, it is too large. I could probably make a vinyl gasket of some sort, but don't want to bother if this is not the correct size.

You might try cutting a piece of PVC pipe (sprinkler pipe) and then cutting it in half again. The two pieces will protect your rail from scratches and act as a washer.

The real Shake had the same problem on my '97ish Montauk. I
tried lots of things off and for about five years. What
finally fixed it was a metal shim. I used a piece of metal
repair shingle (the brown metal you shove under the roof
shingles as a band-aid till it quits raining and you get a
new roof). Dunno what's it's made of, but a magnet sticks
to it, so it ain't SS. I'm amazed that in a couple of years
it hasn't rusted away, but there's ZERO rust. I looked for
SS sheet but it was REALLY expensive.

Vinyl was one thing that didn't work, in a couple of
variations. Neither did duct tape, and a few other things I
don't remember. The steel shim hasn't budged.

A piece of 3/4" thin PVC pipe (the cheesy Schedule 120 (?)
stuff they sell for cheapskate sprinkler systems) might
work. There was a piece of scrap laying on my workbench
from another whaler project, so I just ran a quick
experiment. Cut to length. Then cut lengthwise, removing
about 1/8" of material (otherwise it's too big). It slipped
over the rail nicely. But I'm leaving the shingle.

I just bought the same thing at boaters world online. It has an adapter for 7/8 with it. A thin wall plastic clamshell.

Excellent advice! I bought a 10' 3/4 inch pvc pipe (200psi) for $1.50. (the thin walled stuff). The pipe actually popped right into one side of the mount. Outlined the mount and cut w/ my dremel. Measured the other side and cut. Fits just as snug as my C.E. Smith rod holders and protects my rails too.

Funny, the thin-walled PVC pipe I had was only 125 PSI. Maybe
it's gotten better -- I bought 25 years ago for my first house.
I learned my lesson there used Sch 40 (the good stuff) for
this house. But there was still a piece up in the rafters.

Admiral Linda is quite familar with the problem as she was
usually the one that had to straighten up the antenna. When
I told her about WT's idea to use PVC, and that I wasn't going
to change from the shingles, she said, and I quote: "If it
ain't fixed, don't break it." ;-)
