BHA-100* Broadband House Amplifier Installation Manual
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.
Table 2-2 lists accessories available for the amplifier:

Amplifier accessories
Accessories Function
LC-UL/CSA
3 foot line cord, 125 Vac, UL and CSA rated, NEMA 5-15P to IEC 320
JXP-*B
Plug-in pads (available in 1 dB increments from 1 to 24 dB)
SFE-100-*
Forward cable equalizer for 1003 MHz systems (available in 1 dB increments from
2 dB to 22 dB)
SRE-*-*
Return cable equalizer for 1003 MHz systems ( available in 1 dB increments from
0 dB through 12 dB
SCS-*
Cable simulator that compensates for cable properties and can be used in place of
fixed equalizers where the amplifiers are close together
BHA-100/RA-Kit/L
Return amplifier kit includes all components necessary to activate the return path in
the bandpass from 5 to 40 MHz, 5 to 42 MHz and from 5 to 65 MHz
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*.
