Overview

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*.
