Taco Log Periodic Data Sheet

Models LPD-7 and LPD-12

The LPD-Series antennas are comprised of dipole elements connected to a parellel pair of square Aluminum crossarms that form the antenna transmission line. To accomplish end fire log periodic operation, the elements are tapered from the front of the antenna to the back. These rugged 50 Ohm Log Periodic antennas are maintained at D.C. ground potential through the grounding of the crossarms at the rear of the antenna. A ground wire attached to the crossarm mounting of the cable fitting will drain off static build up and provide lightning protection.
