It make it easier if you think of the loading coil as a transformer: the
current is lower on the "top" but the voltage is higher. Power is the same
(minus losses).

I think it was W8JI who went to great lengths with two thermocouple RF
ammeters to prove the currents were the same at the top and bottom of his
mobile antenna loading coil.

AFAIK, W8JI used the 2 ammeter experiment to show that the c

Sorry Jim K9YC but it is incorrect to say that a loading coil at the base

I'm planning on putting up a 160m Inverted L along with the K2AV FCP. I'm aware
of the other options for radials, etc. but for my particular situation the FCP
seems to be the best option. I also will be supporting the L from the tower
which I know is not the best plan but, again, it's the best o
