40-180 Antenna Disassembly
#2

Hi

Not that I am aware of. Plus, there are fine wires embedded in that paper covering, which is an electrostatic shield for the loop antenna.

In the past, I have pulled off as much of the old rubber insulation as I could, then slipped on the appropriate color of heat shrink tubing to go as far into the antenna as possible, applied heat to shrink the tubing and moved on to the next wire. I did not want to try removing the cover and destroying the electrostatic shield in the cover.

If you really want to remove the cover, the antenna will still work without the electrostatic shielding. Somewhere around here I have the frame of a 1940 Philco "muffler" antenna, which is actually complete except for lack of a cover. I've used it for resting purposes, and it does work without the shielding.
