2
Single Carrier per amplifier and not including Branching Losses.
3
Guaranteed transmit power is 1 dB less.
4
Guaranteed noise figure is 1 dB greater.
5
Supported assigned channel bandwidths: 56 MHz, 40 MHz, and 30 MHz or less. ITU-R F.386 provides for
low capacity channel bandwidths of 1.25, 2.5 and 5 MHz. Certain administrations permit combining
adjacent 28 MHz channels into one 56 MHz channel. US-IRAC channel bandwidths of 5 MHz, 10 MHz,
15 MHz, 20 MHz, and 30 MHz are common. In certain applications, 40 MHz channels are permitted.
6
Minimum T-R spacing (inner channels) requires > 25 dB antenna system return loss per each antenna.
7
Measured from equipment waveguide antenna port in to waveguide antenna port out.
Does not include external feedlines or antennas.
