High-Power TWTA Satellite Terminals Single Thread System Installation
Rev.1 2–7
2.3 TWTA Installation
At the customer’s discretion, the TWTA can be installed anywhere on or near the
antenna. The supplied hardware allows the installer a wide range of installation
alternatives, including:
•
Vertical pole (e.g., mast) (either square or round). This is the most typical
installation.
•
Within the hub of a large antenna.
EFData recommends that the TWTAs be mounted vertically.
Note: A clearance of 2” (5.08 cm) is required for the air inlets and exhaust ports. If the
TWTA is mounted in an enclosed chamber, duct the exhaust air to the outside of the
chamber. Do not re-circulate the exhaust air back into the TWTA. Use an exhaust duct
that is slightly larger than the exhaust port of the TWTA and one that has smooth bends
and transitions.
