Pro Portable Single and Dual Co-Pol TRIA
Date: 04 June 2013
Product(s) Affected: Pro Portable Terminal
Hardware Release Affected: Co-Pol Transmit Receive Integrated Assembly (TRIA)
Summary: A version of the Pro Portable is needed to allow the
system to function while operating in a region that is
covered by both Left Hand and Right Hand Circular
Polarization.
Issue(s)
The country of Saudi Arabia has regions where a deployed Pro Portable requires the unit to be capable of either Left Hand or Right
Hand Circular Polarization. To address the need for dual polarization capabilities, the Pro Portable comes in two configurations: (1)
with one Co-Pol TRIA and the ability to rotate the Feedhorn assembly or (2) with two Co-Pol TRIAs.
Configuration 1 – Requires that end user have access to a clean, low humidity, dust free environment to disassemble,
rotate, and reassemble the unit’s Co-Pol TRIA.
Configuration 2 – Requires the shipment of two Co-Pol TRIAs (one for each polarization) and allows the end user to
assemble the unit with the correct Co-Pol TRIA.
Current documentation for the Pro Portable does not provide instructions on the following:
Beam identification and Co-Pol TRIA modification/selection
Configuration 1 installation instructions
Configuration 2 installation instructions
