COMPARISON BETWEEN 100mW and 1W RADIO TRANSMITTERS

The Mil-Ram radios provide 100mW transmit power and offer excellent range, interference rejection and receiver sensitivity. While more powerful radio transmitters are available, overall Effective Radiated Power is still limited by FCC part 15 regulations at less than or equal to 36 dB. This means that a 1Watt radio must use a lower gain antenna to stay in FCC Compliance compared to a 100mWatt radio for the same Effective Radiated Power.

Since these radios are actually transceivers (transmit and receive) the 1 Watt radio with lower gain antenna is less effective in Receive Mode than the 100mW radio due to the use of a low gain antenna (assume 1 Watt and 100mW radios have equivalent Receiver sensitivity).

The 100mW radio achieves the same Effective Radiated power for transmission as the 1 Watt radio but does not compromise the Receiver with the use of a low gain antenna. The 100mW radio offers the best compromise between Transmit and Receive functions for a Transceiver application. The 100mW radio also draws up to 70% less power in Transmit mode and is therefore ideally suited for solar panel/battery operation.
