Directional Hand-held Antenna (HD-1)
The handheld dipole antenna improves directionality and accuracy for pinpointing leakage sources. The HD-1 increases the
CLI instrument sensitivity compared to the near field probe antenna. The directivity dynamic range of the HD-1 is
approximately 10-20 dB in an outside environment and approximately 5-10 dB in an indoor environment. It is easier to train
new technical staff to understand and operate the CLI System because they get significantly more directionality with the HD-1
and firmware version 6.0 or higher. The HD-1 hand-held dipole antenna picks up RF energy in a directional pattern. This
pattern gives directionality that is crucial in locating leaks. |
