These are non standard pitch, so if you snap them you likely must make your own. Ask me how I know.
Oil plug is M26x1.5
buying one is better, but anything is better than none
with trailer wiring greyed out
A 6 KLP/F AKAC019 made by Geroh GmbH, Germany
Extends 6m long or 20ft
I believe designed to hold a "radio mast spike" as part of the SEM 25 unit
you could easily do an inverted-v dipole and get 1/2 wave length for 12 Meters or 1/4 wave on 20 Meters
Rated for a max head-load of 15kg
Some links:
The original system was likely SEM 25, which operated 24v from about 26 to 70 MHz.
