Table 5-3 shows the RF Power outputs for the transmitter modules in each frequency band.
Table 5-3: RF Power Outputs
Band Frequency Transmitter
VHF Lowband 29 – 50 MHz 0.5 to 3.0 Watts
VHF Highband 136– 174 MHz 2.0 to 8.0 Watts
UHF 400 MHz 406 – 430 MHz and 450 – 470 MHz 0.5 to 2.0 Watts or 2.0 to 8.0 Watts
UHF 800 MHz 806 – 824 MHz and 851 – 869 MHz 0.5 to 3.0 Watts
UHF 900 MHz 896 – 902 MHz and 928 – 960 MHz 0.5 to 3.0 Watts
VHF AM 118 – 137 MHz 1.0 to 3.0 Watts (Carrier Only)
If a higher RF power output is required, the transmitter may be used as an exciter to drive a power
amplifi er. Codan Radio Communications manufactures a 30 Watt power amplifi er for VHF highband
and UHF 400 MHz, shown in Figure 5-8, that will fi t into a standard subrack.

Codan Radio Communications can also supply higher power amplifi ers (60 W, 100 W, 250 W) that are
19” rack mountable, as well as amplifi ers for other frequency bands (Lowband and AM). All transmitters
and power amplifi ers are rated for 100% continuous duty.
