LOG PERIODIC DIPOLES
HIGH POWER, HIGH FIELDS
Two different models are available for generating high fields below 50 MHz. LPD-220s are
designed to operate from 20 MHz to 200 MHz. The LPD-220/A10 and LPD-220/A5 can handle
input powers up to 10 KW and 5 KW, respectively.
The rear elements of the LPD-220s are truncated and loaded to reduce the overall size of the
antenna. Loaded elements at the low end simulate the gain of a full size log periodic antenna. A
wheeled pedestal is supplied to move this large antenna from one place to another. Antenna
polarization may be adjusted manually or remotely using an optional pedestal, model AS-220/T.
