product description


The Dualband Mast-Preamplifier DBA-270 improves the receiving characteristics of
amateur radio stations in the 2-m and 70-cm-Band. Due to the built-in Diplexer only
one HF-socket for the combi-antenna and the coaxial cable has to be connected.

The maximum output power is 100 Watt. As all preamplifiers made by SSB-Electronic GmbH,
the DBA-270 offers direct feeding as well as remote feeding. Direct feeding is done over a
UHF socket, remote feeding the existing coaxial cable is used, as usual. You should connect
a crossover network Type DCC-5000pro. If the transceiver is used in combination with a power
amplifier, we recommend the crossover network Type DCC-5000pro.

The DBA-270 can be switched by the transceiver via the coaxial cable, if the transceiver can
contrrol a mast preamplifier.
