GP 450-3/L PROCOM ANTENNE

380-410MHz

Ground Plane Antennas GP 450-3/...

Colinear, 3 dBd Ground-Plane Base Station and Marine Antenna for the 450 MHz Band

The high gain of this antenna combined with its low height makes it the right choice for a wide variety of purposes.

The antenna is delivered in two models tunable by cutting within 380…410 MHz (l-version) and 406…470 MHz (h-version), respectively.

The GP 450-3/… is especially suitable as a marine antenna in connection with 450 MHz cellular radio telephone systems making it possible to extend the normally land-based cellular system for maritime mobile service as well.

The compactness of the GP 450-3/… also makes it highly qualified as a base station antenna.

The higher the antenna is mounted, the better coverage. Avoid mounting the antenna parallel to or in the neighbourhood of other metal parts such as masts, supporting wires etc., otherwise the SWR and the radiation pattern may be influenced.

The antenna is easily field-tuned following the instructions below, or it can be ordered factory-tuned for CELLULAR or customer-specified frequencies. See ordering information below.

Materials used are 18/8 stainless steel, UV-stabilized plastic and triple-plated chromed brass.

PLEASE NOTE: The GP 450-3/… can also be delivered factory tuned to a specific frequency or cellular network, such as TETRA
