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

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.
