PTA-12 Close-Up
VC28 Mounting:
Refer to drawing ENG-5023 in appendix A. The ENG-5023 drawing shows the mounting
template for the VC28 DC-to DC converter. The template is scaled 1:1 so it can be used to mark
locations for mounting the VC28 to the airframe. The VC28 is located next to the RCOM-100
(see drawing ENG-5021). Prepare the mounting location to provide a good electrical bond
between the VC28 and the airframe. If the removal of paint is required to obtain this electrical
bond it should be done.
Prepare the mounting holes and secure the equipment.
Refer to the picture above (RCOM-100 and VC28 Mounting). The VC28 is just to the left of the
RCOM-100 and is mounted to the equipment shelf.
Route Coax Cables for Tx and Rx:
Refer to Drawing ENG-5021 to see Coax routing location. The coax pair routes from the Antenna
down the right side of the aircraft then back to the RCOM-100. Make sure the correct coax for
the Tx and Rx channels is selected and make sure they are attached to the correct antenna
terminal and RCOM-100 terminal. Refer to the tables above for coax selection. The cables have
a minimum and a maximum db loss and the Tx and Rx are at different frequencies.
The cables
are not interchangeable
.
As the cables are routed from the antenna to the RCOM-100, make sure that the do not interfere
with any aircraft control cables. Secure the cables to the aircraft framework so that they will not
come loose or interfere with moving objects.
