TV broadcast receiving antenna sulfur dioxide test

Sulfur dioxide is recognized as the most important corrosive gas in the atmosphere and can accelerate the corrosion process of most metals. The sulfur dioxide test for television broadcast receiving antennas can measure the impedance of electronic components and connectors in the antenna in an atmosphere containing sulfur dioxide, especially the change in contact resistance in the circuit.
Zhongke Testing Reliability Experiment Center has the reliable performance of various TV broadcast receiving antennas and provides professional sulfur dioxide testing services for TV broadcast receiving antennas.

① Classification according to the band used: long wave, ultra-long wave antennas, medium wave antennas, short wave antennas, ultra short wave antennas, microwave antennas and millimeter wave antennas.
② Classified by use: communication antennas, broadcast antennas, TV antennas, radar antennas, navigation antennas, direction finding antennas, etc.
③ Classified by antenna characteristics: strong directional antennas, weak directional antennas, directional antennas, omnidirectional antennas, needle beam antennas, sector beam antennas, etc.
④Classification according to the current distribution on the antenna: there are traveling wave antennas and standing wave antennas.

The mixed gas in the test chamber should meet the following conditions:
1) Sulfur dioxide (SO₂) 25±5×10^-6 (Vol/Vol)
2) Carbon dioxide (CO₂) 4500±500×10^-6 (Vol/Vol)_{0 3) Temperature 25±2℃ 4) Humidity 75±5%}
