DLP-4620A1 Mobile DF Antenna

An Accurate, Compact Antenna for Mobile Operations


The DLP-4620A1 Mobile DF Antenna is a combination (UHF & L Band) antenna, consisting of four vertically polarized log periodic elements enclosed in a vacuum ­formed, ruggedized, compact, lightweight, abrasive-resistant plastic cover with UV protection.  The DLP-4620A1 is designed to receive vertically polarized signals in the 600 MHz to 3 GHz frequency range providing accurate and repeatable bearings.

The antenna enclosure is designed to be mounted on a steel vehicle roof.  Magnetic mounts are attached to the base to provide stability and facilitate quick and easy vehicle installation. Slots for safety straps are also included.

All power and control signals to the antenna are provided through one 8-conductor control cable from the DF processor. The received signal, with bearing information encoded, is routed to the receiver through a coaxial cable. Control signals are compatible with the DF Processor DFP 1000B produced by RDF Products of Vancouver, WA, USA.
