Most Phantoms have a tuned input capacitor located on the rear panel.
It should be either a screwdriver slot adjustment or a shaft with small knob.
really touchy tuning if your radio has a swr meter just key into the amp and adjust for lowest swr . if no internal swr meter just place a swr meter between the radio and the amps input
