Detailed
Description
Valcom's
BBMT-50 and BBMT-70 consist of matching transformers or baluns
designed to produce a good impedance match between a receiving
antenna and 50-ohm and 70-ohm coaxial cables.
The matching
transformer in both units is of a broadband, toroidal design.
Normally, the standard BBMT-50/70 is used to match one of Valcom's
35-foot vertical whip antennas to a receiver in the frequency
range of 100 KHz to 30 MHz.
Other antenna
heights and configurations can also be matched, but the antenna
must be specified so the optimum transformer design can be used.
If a narrower frequency range is specified, the matching
transformer design is chosen to match the antenna and the
receiving frequency range.
For best receiver
performance, the antenna and operating frequency range must be
specified so the BBMT-50/70 can be designed to give the optimum
matching characteristics.
