●
The maximum of the antenna output signal serves as a directional criterion (maximum
direction finding).
●
Handy size despite extreme broadband capability.
●
Fatigue-free operation due to the antenna design and the material used, which keep
its weight to a minimum.
●
Mainly used for vertical polarization but for test purposes horizontal polarization can
also be used by turning the antenna by 90°.
●
May be mounted on a tripod (¼” mounting thread).
●
Power supply via the connected R&S FSH4/8 through the data and control cable.
1.2 Description
The R&S HL300 comprises the following elements:
●
Log-periodic dipole array antenna with a nearly frequency-independent directional
pattern
●
GPS receiver and electronic compass
●
Toggle switch for activating and deactivating the LNA within the R&S FSH4/8; indi-
cation by adjacent LED
●
RF and control cable (length approx. 1.5 m with N-type connector and control con-
nector)
●
Tripod mounting thread
A green LED on the rear of the supply and display unit indicates activation of the LNA
within the R&S
FSH4/8.
