VHF - UHF Diplexer

VHF/UHF Diplexer for Simultaneous Dual-Band Operation

This diplexer combines separate VHF and UHF antenna inputs into a single RF output, allowing both bands to be used concurrently on one radio.

In typical setups, monoband antennas require individual feedlines and manual switching. This diplexer eliminates that requirement by internally separating and combining frequency bands, enabling parallel operation.

Key Use Cases:

Satellite communication (simultaneous VHF uplink / UHF downlink)
Crossband repeater operation
Dual-band contesting setups

Benefits:

Eliminates antenna switching
Reduces feedline complexity
Enables simultaneous multi-band operation

UHF Power Divider

The TT-UPD-001 UHF Power Splitter/Combiner is a broadband, low-loss passive RF device designed for efficient power splitting and signal combining in UHF communication systems. When used as a power splitter, it divides a single RF input into two equal-amplitude output signals while maintaining excellent amplitude and phase balance. When used as a power combiner, it
combines two RF signals into a common output with high isolation between the input ports, minimizing interaction between connected transmitters or receivers.

UHF Masthead Preamp

The TT-RF-MHB-01500, UHF Masthead Preamplifier is a low noise figure,low thermal noise LNA designed to improve the sensitivity of UHF receiving systems by amplifying weak signals directly at the antenna before transmission through the coaxial feeder. This gives an improved signal to noise performance especially with long cable runs.
