Abstract | The system has special antennas with high gain in a narrow frequency band inside and outside the building and directly and passively connected to an HF line. An external transmit/receive station is connected via an HF line from the antenna with a separate HF connection, an HF coupler and a 3-way HF coupler directly on the low-loss HF line to the antennas in the building. he direct connection of the transmit/receive station antennas is optional. The system has special antennas (1-6) with high gain in a narrow frequency band of 66-500 MHz arranged inside and outside the building and directly and passively connected to an HF line. An external transmission and reception station (13) is connected via an HF line (19) from the antenna with a separate HF connection (11), an HF coupler (10) and a 3-way HF coupler (7-9) directly on the low-loss HF line (14) to the antennas (4-6) inside the building. The direct connection of the antenna of the transmission and reception station is optional.
Passives Funkübertragungssystem, welches die zuverlässige Funkverbindung besonders im Haveriefall, bei Bränden und anderen außergewöhnlichen Ereignissen durch die jeweiligen Einsatzkräfte, wie der Feuerwehr, aus und in das Innere der Gebäude oder der Baulichkeiten zuverlässig gewährleistet. DOLLAR A Die technische Lösung wurde mit einem "Passiven Repeater" gefunden. Dieser besteht aus einer Spezialantenne mit hohem Gewinn, die elektromagnetische Wellen des sendenden Funkgerätes aufnimmt und diese über eine weitere Antenne wieder aussendet, das Gegenfunkgerät diese elektromagnetischen Signale aufnimmt und somit die Funkkommunikation in und aus den Gebäuden und Baulichkeiten gewährleistet. Beide Antennen sind über eine dämpfungsarme HF-Leitung miteinander verbunden. |
