NOTES:
(2) Relief for the specified requirements is permitted if substantiation of Type F Diplexer in
excess of the "Assumed System Rejection to Ant port" can be demonstrated.
E. Harmonics Above the Tx-band (>1670 MHz)
(1) Tx output port referenced harmonics is less than the following limits over the respective
frequency range when used with Type F Diplexer and 1.4 dB of coax interconnecting
cable shown in Table 2-4:

1 Modulated carriers must have unique test sequences from each other.
2 On aircraft equipped with Glonass 5
no more than 30 MHz of carrier separation may be applied if warranted.
3 Limits of Rx band have equivalence to degradation of G/T.
4 Limits within 2 MHz of Tx-band edges apply only if carriers are not present within
2 MHz of that edge of the Tx-band.
