BHA-100* Broadband House Amplifier Installation Manual
2-2 Overview
Several models of the BHA-100* are available to accommodate various forward and return
bandpass requirements, as described in
Table 2-1
BHA-100* models
Table 2-1:
Model Number Forward Bandpass Return Bandpass Output Stage Forward Gain
BHA-100S/P-R
BHA-100K/P-R
BHA-100A/P-R
52 to 1003 MHz 5 to 40 MHz Power-doubled 34 dB
54 to 1003 MHz 5 to 42 MHz Power-doubled 34 dB
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.

The forward amplifier consists of a low noise pre-amplifier followed by a power-doubled output
stage to achieve low distortion. Between the two stages there are gain and slope controls for
level adjustment.
The input signal level to the pre-amplifier is controlled by a vari-losser with a range of 6 dB.
The vari-losser is controlled by the
GAIN potentiometer. A JXP-*B socket is also incorporated in
the signal path to further reduce input signal amplitude. SFE-100-* cable equalizers can be
installed in the socket to supplement the slope control network.
A –20 dB directional coupler test point at the amplifier input monitors forward input signal
levels. Directional coupler test points are also available to measure forward amplifier output,
return input, and return output signal levels.

Accessories and Options
You can upgrade all models to accommodate two-way service by installing an optional return
amplifier kit, model BHA-100/RA-Kit/L. This kit enables the unit to carry channels in the
extended bandwidth return path. Cable equalizers and plug-in pads are also available to
enhance equipment performance.

Return Amplifier
Diplex filters for two-way operation are permanently installed at the input and output ports of
the amplifier. The BHA-100* employs three return bandpasses: 5 to 40 MHz, 5 to 42 MHz, and
5 to 65 MHz. You can add the return amplifier function to the BHA-100* by installing the
return amplifier hybrid and the return equalizer, model SRE-100*. Additionally, there are
JXP-ZX jumpers for the JXP-*B pad sockets to establish continuity for the return path.
You can use directional coupler test points to monitor signal levels at both the input and output
of the return amplifier.
Cable Equalizers
Cable equalizer model SFE-100*-* can be installed at the amplifier input. This equalizer
compensates for tilted signal levels due to cable attenuation versus frequency. Using the
equalizer results in lower signal levels at the lower channels. The equalizer compensates for
cable signal loss in 1 dB increments.
You must remove the ergonomic plastic shell before you install the SFE-*-* in the BHA-100*.

3-6 Configuration and Installation
Figure 3-3 shows the equalizer slope versus equalizer value information presented in Table 3-1
as a graph. The amount of cable equals the equalizer value.
Figure 3-3
Equalizer slope versus cable
Refer to Figure 3-3 to determine the proper cable equalizer for the BHA-100*. For example, the
input tilt derived from a channel near 550 MHz and a channel at the low end of the bandpass is
6 dB. According to the graph, the appropriate (closest) equalizer is model SFE-100-8.
7 Install the selected cable equalizer in the amplifier.
8 Connect a signal level meter to the amplifier output and tune the meter to the highest
frequency on the system near 550 MHz.
9 Turn the gain control fully clockwise, and then reduce the gain by 1 or 2 dB, as indicated on
the signal level meter.
10 The signal level should be at the proper output level as noted on the system drawings. If the
level is excessive, install JXP-*B pads to reduce the signal to the proper level.
11 Tune the signal level meter to the low end of the band. Turn the slope control fully
clockwise, and then reduce the channel level by approximately 2 dB with the slope control.
The output tilt of the amplifier, between 52 MHz and 550 MHz, should be 10 dB.
12 If necessary, use the slope control to make corrections of 1 or 2 dB. Change the cable
equalizer if greater changes are needed to achieve the desired output tilt. Use a higher
value equalizer if the tilt is less than desired and a lower value if it is more than is required.
13 Replace the inner and outer covers of the amplifier.
