The IPLD does not require forced cooling. However, to ensure that the IPLD can
dissipate heat, install the IPLD in a location that meets as many of the following
conditions as possible:
• temperature controlled
• air can circulate around the IPLD
• the IPLD can dissipate heat to that aircraft structure.
Install the IPLD:
• so that the maximum transmit cable loss between the HDU and IPLD is 28dB
• so that the maximum receive cable loss between the HDU and IPLD is 25dB
NOTE:
Honeywell recommends RG142B cable for both transmit and receive
connections. The transmit loss in 50 feet of cable is about 10dB.
• so that the maximum cable loss between the IPLD and the antenna is:
• 0.3dB for an LGA
• 0.8dB for the IGA or HGA
• 0.3dB for the AMT-3800 HGA in Swift 64 configuration.
NOTE:
Honeywell recommends Carlisle cable 311701. The transmit loss
in five feet of cable is about 0.3dB. There is an additional loss of
0.01dB in each connector.
The IPLD has four connectors.
