Description

150 W HF Dipole
Key facts HF dipole antenna for use in stationary applications The HF Dipole R&S®HX002H1 is suitable for setting up radio links over any distance. In particular, the optimized omnidirectional coverage ensures high transmission reliability over short and medium distances. R&S®HX002H1 can be operated together with the 150 W HF transceivers out of the SERIES 4100 family. The extremely fast setting time of R&S®HX002H1 allows frequency hopping operation in line with R&S®SECOM-H. The antenna enables silent tuning across the entire 1.5 MHz to 30 MHz frequency range. For this, the integrated tuning unit must first learn the correct tuning settings for the antenna in a user-defined frequency range. Thereafter the antenna achieves tuning times of <5 ms. Particular attention was paid to obtaining an effective lightning protection. The ATU is fully arc-protected against direct lightning strokes. It is tested to withstand arcs of 10 kV/10 kA.
