Page 5: Characteristics
® Characteristics R&S HL300 1 Characteristics 1.1 Use The handheld log-periodic antenna R&S HL300 in conjunction with portable spectrum analyzers (for example the R&S FSH4/8) is used to determine RF parameters and local- ize potential interfering sources. The direction of signal sources is found by pointing the antenna towards the direction of maximum signal voltage. -
Page 6: Description
® Characteristics R&S HL300 Description ● 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. -

Page 16: Notes On Practical Use
® Operation R&S HL300 Notes on Practical Use The toggle switch remains in its position ; to deactivate the LNA move the switch back into position “OFF”. 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. - Page 17 ® Operation R&S HL300 Notes on Practical Use If an unambiguous maximum is not obtained in a closed room, for example, the interfer- ence due to reflections is too high and the site has to be changed. Reflections and interference occur if electromagnetic waves come into contact with objects that have a high dielectric constant or are conductive.
