Strong support in Congress from a number of senators, including Lyndon Johnson and Hubert Humphrey, contributed to NTCA's success in strengthening the rural telephone program. Path loss is proportional to frequency squared and antenna gain is also proportional to frequency squared, so as gain appears twice in Eq. (6.1), the received carrier power is proportional to frequency squared. The minimum subjective quality level is the main point of discussion these days. A reliability of 99.999 percent would be an excellent target to achieve, and most common carriers in North America design their protected radio system paths for this level of availability.
