Parabolic & dish
Building an antenna
Parabolic grid & dish antenna
Difference between this two antenna types is that parabolic antenna has metallic grid for reflector and dish has a solid reflector.
This highly directional antenna type transmit/receives signals in a very narrow angle, so they are ideal for long distance and point to point network connections.
It has a main reflector surface that is shaped like a paraboloid or sphere with an active element at its focus. That way reflector surface can reflect parallel signals to a single focal point.
Parabolic & dish antennas are the best choice because very narrow beamwidth will provide you:
- minimum interference with another wireless networks
- longest signal distance & faster link
- improved security (especially if they are mounted high)
