Looking for a neoprene washer for the AB15 antenna if anyone has one available.
DISREGARD. Made one out of a tire patch.

Detail C in this drawing doesn't show any washers between AB-15 and MP-50.

That only means the AB15 when installed on the MP50 doesn't require any separate washers on the radio set instructions. The washers you are concerned with may only show up on a detailed parts list or drawing for the AB15 specifically. You need a copy of the Parts List for the AB-15/GR antenna base. TM 11-5985-230-14P.

Neoprene washers are available in a couple of thicknesses
and several diameters at some big box hardware and home garden stores
as well as Tractor Supply and others.
They might not be dead on, but failing to find
a real part may do in a pinch.
You can also buy 1/16" neophrene sheet.

Brian,
Didn't know about the sheets. I'll be driving by a TS today so I'll stop in and see if they have it. Thanks.

I've bought 1/8" thick neoprene sheet online.
I've also bought neoprene or rubber washers at Lowe's I've
used for the pedal draft pads instead of felt.
Pretty sure they are 1/8" thick, not sure of the diameter.

You guys did notice this in the specs I posted??
ABNM THICKNESS 0.062 INCHES NOMINAL
0.062 = 1/16" thick.
These neoprene washers are really gaskets meant to seal and not meant to provide additional flexing of the base. You'll find the collective additional 1/8" of spongy material will allow too much flexing of base. Shop for 1/6" thick sheet or rolls at least 3" wide.

Yes I knew the spec was .0625.
I was pointing out that thinking out of the box opens
up other avenues for parts.
I do know Lowes sells rubber gaskets 1/16" or .0625"
thick. I'm not sure of the diameter or hole size.
Another source would be auto parts stores. They sell gasket
sheeting in various thicknesses.

I'm going to head to the auto parts store this AM and get the sheet then use my existing one to make a new one. Struck out @ Lowes and also ACE. Had not thought of an auto parts store. Thanks everyone for your input.
