Locomotive antennas PA-420, PA-450 and a new series of models "LA" are purposed to be exploited in the railroad communications systems within the range 405-470 MHz. The equipment of TETRA standard that works in this range as well as the data transfer system may include these mobile antennas. The models PA-420 and PA-450 are all-metal quarter-wave loop vibrators. Their construction provides the direct grounding and the electric shock protection. The "LA" models have low-profile construction, their height does not exceed 80 mm and they are protected by a strong case made of ABS-plastic. This ensures the improved aerodynamic characteristics and additional electrical safety of this antenna. The construction is grounded by direct current.
