There are 2 visual anomalies

I know it is a coil of thick enameled wire with a diameter of approx
25 mm ( 1 inch ) but do not know its inductance .
So in order to make one myself I would appreciate receiving info re
the dimensions incl number of turns ,alternatively the required
inductance.

2)The antenna kit is normally supplied with a specific length of 75
Ohms coaxial cable directly connected across the inductor (see above)

This length of 75 ohms coax is part of the matching system and is to
be connected to any length of 50 Ohms coax running to the transceiver.
In the Pictorial ,page 14 of the manual ,this length of 75 Ohms coax
is identified by 'R'.


TIA for any relevant info

Hi Frank:

I can't help with the coil, but the coax is 1/4 wave length at 20m.
