SSB DBA 270 Duoband 2M/70 CM

Boost your amateur radio signal reception with the SSB DBA-270 dual-band preamplifier, specifically designed for the 2-meter and 70-cm bands. This high-performance preamplifier is ideal for optimizing dual-band antennas, providing improved reception and performance.

Benefits of the DBA-270 Dual Band Amplifier

• Dual-Band Compatibility: The DBA-270 is dual-band antenna compatible and improves signal reception on both the 2 meter and 70 cm bands. For monoband antennas, an antenna switch is required.
• Split band design: Prevents interference between the two frequency bands by using separate amplifier stages with diplexer circuits.
• Automatic Transmit/Receive Switching (VOX): Automatically switches between transmit and receive, with a maximum switchable power of 100 watts in VOX mode. For higher powers a sequencer is used.
• Remote Power: Can be powered remotely via coaxial cable or locally via UHF connection.
• Impedance Protection: Input and output circuits are optimized for an exact 50 ohm impedance, which is essential for the performance of modern narrowband antennas.

Robust construction:

• Weatherproof housing: UV-resistant and weatherproof housing with N-sockets.
• Includes mounting hardware: Supplied with hot-dip galvanized clamps and stainless steel mounting hardware.
