What it does
A 10-turn RHCP helix tuned across the lower GNSS L-band — covering GPS L5 at 1176.45 MHz and GPS L2 at 1227.6 MHz. Suitable for civilian dual-frequency GPS monitoring and indoor-navigation testbeds where a directional helix is preferred over a patch.

Sicherheitshinweise
Passives Bauteil ohne eigene Stromversorgung. Sendebetrieb: Die Einhaltung der Grenzwerte für die Exposition durch elektromagnetische Felder sowie der geltenden Betriebs- und Amateurfunkbestimmungen liegt in der Verantwortung des Betreibers. Während des Sendebetriebs nicht an Antenne, Speisung oder Reflektor arbeiten und ausreichenden Sicherheitsabstand einhalten. Montage: Für den Einsatz im Freien vorgesehen. Auf sichere Befestigung an Mast oder Spiegelarm achten. Klemmschrauben nur mäßig anziehen – zu hohes Drehmoment kann die Kunststoffteile beschädigen. Arbeiten in Höhe nur mit geeigneter Absturzsicherung. Kein Spielzeug; nicht für Kinder geeignet.
English: Passive component without its own power supply. Transmitting: compliance with electromagnetic field exposure limits and with the applicable operating and amateur radio regulations is the responsibility of the operator. Do not work on the antenna, feed or reflector while transmitting, and keep an adequate safety distance. Mounting: intended for outdoor use. Ensure secure attachment to the mast or dish arm. Tighten clamping screws moderately only – excessive torque can damage the plastic parts. Work at height only with suitable fall protection. Not a toy; not suitable for children.
