Radar installation and commissioning

requirements

• A horn antenna will match better than a rod antenna for 6 GHz radar

transmitters.

This will result in lower noise levels on the signal as well as improved accuracy.

• Horn diameter must match the pipe diameter.

A horn diameter that is smaller than the pipe diameter could result in significant

measurement errors due to alternate mode interference.

• Obstructions in the pipe may include the vent connection, slots, or holes.

Orient the radar "e" field towards these obstructions to minimize their interference.

Bypass pipe installation

① Vent
