Log Periodic Array Broadband Antennas
The SITCO EML and ECL-Series log periodic dipole arrays are designed for medium gain, broadbanded receiving
applications. The ECL-Series is designed for applications requiring the extra gain.
These arrays are durably constructed of high grade aluminum alloys with the mechanical strength required to
withstand the extremely adverse weather encountered at many sites. All elements are sleeved solid rods with
rounded ends.
SITCO EML and ECL-Series have been carefully designed to provide maximum gain flatness over any given
channel within the antenna’s passband, crucial to receiving accurate color information.
The SITCO ECL and EML-Series antennas are constructed of 6061-T6 aluminum alloy. All booms are of tubing
with a wall thickness of .058" for strength and durability. All elements are solid 3/8" rod with a 1/2" x .058" sleeve for
added strength, and to reduce metal fatigue induced by vibration in high winds. All elements have rounded ends to
allow a continuous, low-level static discharge, greatly reducing noise caused by static buildup and subsequent
sporadic high level discharge.
