A method estimates a signal to noise ratio (SNR) of a received direct sequence spread spectrum (DSSS) signal. Using the estimated SNR, a control signal is determined that is suitable for modifying a position of a directional antenna. The control signal may be used to modify the position of the directional antenna. In another method, a first estimated SNR is determined for a received radio frequency (RF) signal. An output voltage of an AGC circuit is converted to a second estimated SNR. Using at least the first estimated SNR when the first estimated SNR is within a first range and using at least the second estimated SNR when the second estimated SNR is within a second range, an output SNR is determined. The output SNR may be used to determine the at least one control signal, which may then be used to modify the position of the directional antenna.
