BARRETT 4050 HF SDR TRANSCEIVER - OPERATING AND INSTALLATION MANUAL
If a tunable transmitter is available, determine at what frequency the best
VSWR is obtained. If this occurs at a frequency below the required frequency
the dipole is too long, if it occurs on a frequency higher than the required
frequency then the dipole is too short. Drop the dipole and adjust both ends
by an equal amount and repeat the above sequence until an optimum VSWR
is obtained. If a tunable transmitter is not available, use a method of trial and
error shortening or lengthening the dipole ends, a little at a time, until opti-
mum VSWR is obtained. Remember to always adjust each end by the same
amount as the other every time.
