Portable radio direction finding device

Abstract

A portable radio direction finding device disclosed by the present invention comprises wireless direction finding equipment and a placement box matched with the wireless direction finding equipment, a plurality of partition plates matched with the wireless direction finding equipment are uniformly and fixedly installed on the inner side wall of the placement box, and a plurality of universal wheels are uniformly installed at the bottom end of the placement box. Each universal wheel is provided with a locking device, a telescopic pull rod and a handle are mounted on the top wall of the placement box, a plurality of fixing devices matched with the wireless direction finding equipment are arranged in the placement box, and each fixing device comprises a positioning frame. According to the portable wireless direction finding device, the wireless direction finding equipment is uniformly placed in the placement box, so that the wireless direction finding equipment can be conveniently carried, and the fixing devices matched with the wireless direction finding equipment are arranged in the placement box, so that the wireless direction finding equipment can be prevented from shaking or vibrating during carrying; therefore, the radio direction finding equipment can be prevented from being damaged in the carrying process, the design is reasonable, and the practical effect is good.

Description

technical field [0001] The invention relates to the technical field of radio direction finding, in particular to a portable radio direction finding device. Background technique [0002] The radio direction finding device refers to a radio receiving device capable of determining the direction of the radio transmitting station, which can be used for ship positioning and search and rescue, etc. It is basically composed of antennas, goniometers, receivers, direction indicators and speakers. Composition, the principle of direction finding is based on the 8-figure pattern of the loop antenna. When the loop antenna is turned to the position where the sound of the receiver is the smallest (dumb point), the vertical direction of the loop antenna plane is the direction of the transmitting station under test. The direction is usually visually measured, the operating distance is 100nmile during the day, 50nmile at night, and the direction finding accuracy is ±2°~±5°. The advantages are ...
