For stationary use or for shipboard applications

R&S HX002H1/H2 HF dipoles with ATU permit optimum coverage of all distance ranges. They are particularly useful for radiocommunications over short and medium distances, because the skip zone hinders transmission reliability of rod antennas at distances of less than 1000 km. The fully automatic ATU integrated in the antenna provides perfect matching to the transmit system, enabling full use of its RF output power capabilities. It features extremely short switching times due to the preset silent tuning channels (1420), and enables ALE frequency hopping in line with R&S SECOM-H with transmitters in the R&S XK4100 and R&S M3TR radio families.

Features & benefits

High RF power at small antenna

The R&S HK002H1 features relatively small, 5 m long, dipole based radiators. The R&S HK002H2 dipoles are even shorter, just 2.5 m each due to limited space onboard ships. The integrated fully automatic antenna tuning unit provides perfect matching of these radiators to the transmit system, enabling full RF output power capabilities up to 150 W.

High efficiency

The R&S HX002H1/H2 uses only low-loss capacitors and air-core coils for matching and has no attenuating measures such as resistor-damped structures. This is more efficient and sends more power into the airwaves.

Omnidirectional coverage with high-angle radiation

The R&S HX002H1 HF dipole is suitable for setting up radio links over any distance. The optimized omnidirectional coverage specifically ensures high transmission reliability over short and medium distances.

Single mast installation

The R&S HX002H1 and the R&S HX002H2 need only one mast for installation. Power is supplied via the HF cable and a fiber-optic cable is used for controlling. This reduces cost, effort and space requirements and increases reliability.
