UHF Antenna

Basic Price € 2500

4 monopole antennas are connected to the splitter output to assemble a complete turnstile antenna system. Either turnstile or quad monopole configuration is possible for UHF band. NanoAvionics can provide deployable antenna systems integrated with a splitter or a customer can implement his own solution.

Splitter consists of RF input connector, a matching circuit and 4 RF output connectors. It is a key element in turnstile or quad monopole antenna systems which splits one RF signal into a phasing network in order to form a single circular polarized antenna. This results in almost omnidirectional radiation pattern with no blind spots, which can cause signal fading due to tumbling satellite. An aperture is provided inside the splitter board for hardware integration purposes.
