The relationship between the selection and layout of wireless microphones and receiving antennas

Author:admin   AddTime:2021-07-27

The receiving antenna of the wireless microphone is one of the larger areas that is misunderstood.

Antenna selection, layout, and wiring errors can all lead to short performance coverage areas and low signal strength, resulting in frequent disconnections.

The performance of modern diversity receivers is far superior to that of a single antenna type, but to optimize system performance and reliability, antenna selection and layout must be correct. So how to solve this problem? First of all, it is necessary to ensure the good diversity performance of the system, and the antenna space must be at least one half wavelength.



The angle of the receiving antenna should be a "V" configuration, which can provide better signal pickup performance when the transmitter is moved or placed at different angles. If the receiver is installed far away from the performance area (such as in the equipment closet or enclosed rack), a half-wave antenna or directional antenna (preferably above the audience) should be installed remotely, so that there is a clear view between the transmitters. Boundary line of sight. Do not install ¼ shortwave antennas remotely because they use the receiver case as a ground antenna. The extra distance between the antennas will not significantly improve the diversity performance of the system, but it may better cover a larger area of the stage, church or conference room. If the antenna is installed far away from the stage, you can use a directional antenna to improve signal reception by picking up more signals in this direction and reducing signal pickup from other angles. If a coaxial cable is used to connect the antenna to the receiver, it may be necessary to use an antenna amplifier to solve the problem of signal loss in cable transmission.

The loss of the signal quantity depends on the specific length of the cable and the cable type. Therefore, please calculate according to the manufacturer's recommendation. The total net loss of the signal should be controlled within 5dB.
