6.2M Rx-only Antenna Product features
Antenna reflector&back structure
Panel is the key component of antenna reflector. The single piece panel of 6.2m antenna is stretching formed through panel envelope and back structure reinforcing rib, then revieted together on evolope revieting table, so the molding panel is with high precision and rigidity. Each set of back structure and pull rod is made of round steel pipe. One end of back structure is connected with hub and the other end is connected with panel. On the key connections of back structure, reflector and hub, there are fixed position pins to provide stable support structure for antenna reflector. It not only guarantees the antenna surface accuracy but also improves the antenna anti-wind and anti-seismic ability.
Antenna kingpost&AZ&El mechanism
6.2m antenna AZ&El mechanism adopts manual drive mode, turbine and worm drive makes the AZ&El drive more convenient and easier. The kingpost and hub adopt superior steel forming through once stretching and revieting to improve the antenna anti-wind and anti-seismic ability greatly.The steel components, such as antenna pedestal and back structure, all adopt hot-dip galvanizing or hot zinc-spraying firstly, and then treat with finishing coat, which all strengthen the corrosion resistance ability of antenna.
