Microwave Antennae Installation Tutorial



 
Microwaves;
Microwaves are electromagnetic waves with frequencies ranging from 300 MHz to 300 GHz.
Frequency bands used for Microwave transmission are 7G/8G/11G/13G/15G/18G/23G/26G/32G/38G.
It is used for transmitting and receives the signals in point-to-point communication systems.

Microwave Link;
Microwave links is used for transmitting and Receive high data capacity .Microwave is used instead of transmission lines.

Microwave Link Installation consideration;
1) Line Of Sight
2) Fresnel Zone
3) Antenna height
4) Frequency band
5) Capacity
6) Modulation
7) Polarization
8) Antenna size
9) Trans and receive level
10) Orientation angle
11) Antenna alignment
12) Installation tools
13) Installation Material
