### He posted a diagram in his 4th posting. His coax to vertical on roof is
just 2.5M long.
He also has 9 M of grnd wire from metal to the dirt. He has a xcvr + 500 w
amp. He probably
requires ferrite at both the base of the vertical..and also in the shack....
IE: both ends of the coax.

Understood. But more questions.
You say 500 watt transmitter. Most ham transmitters are 100W output, and
if you want more power, you add a power amplifier. Is this a 500W
transmitter all in one box, or two boxes?
Where does this cable run? Inside the transmitter, from one point to
another, or outside the transmitter, between boxes? What is the
transmit frequency?
What kind of cable is it? Coax or two conductors plus shield? What
kind of shield? What kind of circuit is connected to the cable at each
end? Balanced or unbalanced? Where is the shield connected?
