Transmitter Equipment Slot Antenna
VISION TECHNOLOGY - UHF Slot Television Transmitting Antenna
VISION UHF slot television transmitting antenna is used in UHF (frequency range in: 470-862MHz) electromagnetic signal radiation products. And it belongs to the wireless digital television signal antenna and the wireless analog television transmitter antenna. The design method of infinite ideal metal surface slotting is adopted. Antenna polarization mode is horizontal pole.
Features
- The antenna adopts multi - channel transmission technology and has higher gain and more - uniform horizontal radiation pattern.
- long effect distance, uniformly covered field intensity, small standing wave ratio.
- The antenna cavity is made of aluminum plate with degree of finish, and the antenna feeder system is all made of silver plating.
- High strength, low loss glass fiber materials are used.
- High stability, low feed loss, strong corrosion resistance.
The feed system of slot antenna is accommodated in the inner part of antenna cavity
Compact, miniaturized, low feed loss, plus the feed system is all sealed in the radome, therefore, the antenna is equipped with the features of compact, strong sealing, high stability.
