CatalogueA TETRA combiner is an RF device used in TETRA (Terrestrial Trunked Radio) systems to combine multiple transmit or receive channels onto a single antenna or a reduced number of antenna ports.
Function
⭐Combines multiple TETRA base station transmitters into one antenna system.
⭐Helps save antenna space and reduces tower loading.
⭐Ensures high isolation between channels to prevent interference.
⭐Maintains low insertion loss so transmit power and coverage are not compromised.
⭐Provides frequency-selective or broadband combining, depending on system needs.
Application
It is essential for public safety, emergency services, transportation, and critical communications networks where reliability and channel efficiency are crucial like the following fields.
⭐Tunnel
⭐Police cars
⭐Fire Trucks
⭐Critical Communications
