BHA-100* Broadband House Amplifier Installation Manual
Several models of the BHA-100* are available to accommodate various forward and return
bandpass requirements, as described in
Table 2-1:
Table 2-1
BHA-100* models
Model Number Forward Bandpass Return Bandpass Output Stage Forward Gain
BHA-100S/P-R
52 to 1003 MHz 5 to 40 MHz Power-doubled 34 dB
BHA-100K/P-R
54 to 1003 MHz 5 to 42 MHz Power-doubled 34 dB
BHA-100A/P-R
85 to 1003 MHz 5 to 65 MHz Power-doubled 34 dB
The recommended difference in signal level between the low and high ends of the specified
bandpass is the amplifier output tilt. The recommended output tilt for the BHA-100S/P-R,
BHA-100K/P-R, and BHA-100A/P-R is 7 dB between 50 MHz and 550 MHz plus 4.5 dB between
550 MHz and 750 MHz, for a total of 11.5 dB.
For maximum security and durability, the BHA-100* is enclosed in a cast aluminum housing
with a heavy gauge cover. The housing is equipped with substantial heat sinking for efficient
heat dissipation. The BHA-100* is designed to be wall-mounted with external mounting
brackets molded in the housing for ease of installation.
The BHA-100*-R is equipped with standard built-in diplex filters at its input and output. When
two-way operation is needed, you can easily upgrade it by installing the appropriate return
amplifier (BHA-100/RA-Kit/L).
Power Supply
The BHA-100* contains an auto-ranging switching power supply that operates from 90 VAC to
240 VAC without adjustments. The power supply furnishes the 24 VDC required by the forward
and return amplifiers.
The BHA-100* is a Class 1 apparatus that requires a protective ground wire in the power cord.
For permanent wiring, a ground must be provided by the third conductor in the power cable. A
short power cord with an IEC 320 connector is furnished for power input connection to the AC
power line. This connector accepts standard domestic power cords and power cords from other
countries.
