Systems and methods for autonomously operating an antenna assembly. The methods comprise: obtaining, by a processor of the antenna assembly, first information comprising at least one of a value for a variable altitude of the antenna assembly, a value for a variable height of the antenna assembly above ground, a value for a variable height of the antenna assembly above sea level, a value for a variable distance of the antenna assembly from a reference object, and a first value for a variable signal frequency of a communication device; using, by the processor, the information to obtain a desired length of an antenna of the antenna assembly; and controlling, by the processor, an actuator to adjust a length of the antenna until the length reaches the desired length.

Systems and methods for operating an antenna assembly. The methods comprise: receiving, at the first circularly polarized antenna, a first signal comprising a desired signal emitted from a first signal source located at a first altitude higher than a second altitude of the antenna assembly and an interfering signal emitted from a second signal source located at a third altitude lower than the second altitude; receiving the interfering signal at the second circularly polarized antenna (where the first and second circularly polarized antennas are disposed on opposite sides of an antenna reflector and having opposite circular polarizations); generating a second signal by shifting a phase of the interfering signal which was received at the second circularly polarized antenna by an amount to cause the second signal to be out-of-phase with the first signal; and providing an antenna pattern with a null at or below a horizon by destructively combining the second signal with the first signal.
