3.4 Notes on Practical Use
3.4.1 How to hold the R&S
HL300
To ensure optimum DF results, you have to carry the R&S
HL300 with your arm stretched
out for locating the maximum.
Fig. 3-5: Manual direction finding by locating the maximum.
The center of rotation should be located in the antenna rather than your body. Moving
the antenna to and fro is unfavorable since the search for maximum reception is impaired
by site-dependent level differences occurring in disturbed electromagnetic fields.
