Verify that you are installing the HDU-409 with the following compatible 
HiGain outdoor enclosures. For a list of compatible non-ADC enclosures, see the 
HDU-409 List 1 and List 2 technical practice, section number 150-409-100-xx.

2

Verify that you are installing the HDU-409 with compatible line and remote 
circuit modules (see 

Table 1

 inside)

.

3

Determine the number of doublers the circuit can support based upon:

the model of the HLU and HRU in the circuit (see 

Table 1

)

whether the HRU is locally powered or line-powered (see 

Table 1

)

whether you are installing in a HiGain (see 

“HiGain Doubler Applications”

or PG-Flex application (see 

“PG-Flex Doubler Applications”

).

4

Observe the following deployment rules for enclosure placement:

Rule 1: Place the enclosures at the electrical limits (35 dB) of each span.

Rule 2: Make all spans the same electrical length (same 196 kHz loss) to 
achieve optimum performance if Rule 1 is not applicable.

Rule 3: To minimize power consumption and dissipation of the HLU, 
confirm that the spans closest to the HLU are as short as possible and the 
spans furthest from the HLU are as long as possible. 

5

Determine the enclosure model based upon doubler and repeater capacities of 
occupied slots as shown in 

Table 2

 

“Outdoor Enclosure Capacities with Full 

Solar Load”

.

The HiGain

®

 HDU-409 List 1 and List 2 are low-power micro doubler units that 

extend the range of a HiGain repeaterless T1 transmission system. The doubler units 
are installed between any doubler-compatible HiGain Line Unit (HLU), HiGain 
Doubler Unit (HDU), or HiGain Remote Unit (HRU). Each doubler allows 1.544 
Mbps transmission over an additional Carrier Service Area (CSA) range.

The HDU-409 List 1 is only compatible with the HiGain product line. The HDU-409 
List 2 is compatible with both the HiGain and PG-Flex product lines. The CSA 
includes loops up to 12,000 feet (3.657 km) of 24 AWG or 9,000 feet (2.743 km) of 
26 AWG wire.
