It is recommended to use flexible waveguide/coax RF interface and with interconnect losses
not exceeding 0.6 dB on the transmit path and stay within 0.5 to 2 dB on the receive path
between the KRFU and the TMA assembly.
The typical KRFU LRU and TMA assembly (swept volume model of antenna shown)
interconnect arrangement is shown in Figure 4-13.
Figure 4-13. KRFU and TMA Interconnect Arrangement
(a) TMA Bonding Requirements
The ground straps are installed before proceeding with ins
tallation of the TMA assembly
on the antenna adapter plate or on the tail empennage airframe structure. The TMA
assembly and KRFU must be bonded to the airframe.
Consult the airframe manufacturer for the correct torque values.
(b) OAE TMA Installation Procedure
Before doing any installation procedures, the installer must read and be aware of the
safety advisories listed in this man
ual. Only authorized technical personnel who are
trained in general aviation workmanship and have a basic understanding of satellite
communication systems should proceed with the following installation procedure.
1 Connecting the Tx waveguide and RF Rx coax interfaces to the TMA per Step (c).
2 Positioning and installation of the TMA assembly onto tail tip antenna slot/antenna
interface mount; installation of bonding straps per Step (d).
3 Installation of the KRFU and bonding straps per Step (e).
4 Installation of the waveguide and coax between the TMA and KRFU per Step (f).
5 Connecting the TMA interface, KRFU power, and control interfaces per Step (g).
