@ a frequency of 27.205 mhz. the difference is 13.25 inches. it's easier to shorten an element if length is excessive than it is to add length to an element that is too short.
in free space: 585 / 27.205 = 21.50' or 258.04"
over real earth: 615 / 27.205 = 22.60' or 271.27"

i would also strongly suggest that you limit the maximum total output of the amplifier to 3.2KW. the next "weakest link" could reveal itself at any time as long as you insist on exceeding the rated output of the total devices in use. the increase from 3.2KW to 4.5KW yields an increase of only...
the series equivalent input and output impedances of a 2SC2879 represent complex impedances due to the capacitive reactance present.
output Z = R1.45 -jX1.0
output Z = sqrt Rsq + jXsq
output Z = sqrt 2.1025 + 1
output Z = sqrt 3.1025
output Z = 1.761391495380854 ohms complex output impedance...
Z (Impedance) = E (Voltage) / I (Current)

The Commission grants the Cobra Petition to the extent described in the Memorandum Opinion and Order on Reconsideration. Specifically, the Commission amends Section 95.971(a) of the Commission's rules to permit CB Radio Service transmitters to transmit FM voice emissions along with AM. The...
the center pin @ the SO-239 connector is shorted through the smaller of the two inductors of the matching auto transformer and back to the shell of the connector.
there is no continuity between the connector center pin and the far end of the vertical element due to the rf coupling capacitors...
