            RFS RADIO FREQUENCY SYSTEMS HLP SERIES

            GENERAL DESCRIPTION


            HORIZONTAL LOG PERIODIC DIPOLE ARRAYS - HLP SERIES

            photo RFS Radio Frequency Systems HLP Series The HLP Series Log Periodics are directional, horizontally polarized antennas designed for medium to long range communications.

            Although virtually ground independent and exhibiting radiation patterns consistent over the entire frequency range, take off angles and frequency bands can be tailored to suit specific customer requirements and applications.

            Side lobes are also low over the entire operating frequency of these antennas, providing good discrimination against interfering signals.
