Mine looked the exactly same. You could substitute my pictures for yours
with the exact same content! I had to replace all four coils.

This is why some people appear bright until you hear them speak.

before that for about 12 years, has the original shrink wrap and screws, and
I've had no problems. But others have had trouble with the screw/wire
connection after some years of service. I have repaired these with a
stainless through-bolt and lock nut.

> I purchased a Cushcraft XM-240 which was new in the box but was made about
10 years ago. The label on the box says "Cushcraft XM-240", and doesn't
mention MFJ, so perhaps it was made by Cushcraft. My questions pertains to
the 4 loading coils. I believe the loading coils made by MFJ have heat
shrink tubing over the coil, is that correct? The loading coils on this
XM-240 don't have heat shrink tubing over them, rather the coil is covered
with a thick shiny black epoxy which is very hard. The epoxy has really
sealed up the coils and self tapping screws that connect the coils to the
aluminum tubing. I believe the epoxy would be rather difficult to remove so
I'm wondering if I'm likely to have reliable results using the traps "as-is"
for a couple years, or if I should remove the hard epoxy from the self-
tapping screws now and replace them with screws, nuts, and lock washers? If
I do replace the screws, should I cover them with more epoxy, use heat
shrink tubing, or both? Thanks
