The Mesa Antenna Measurement Facility has six outdoor far-field antenna ranges. The six Mesa outdoor antenna ranges include three short ranges nominally less than three hundred feet in length and the three long ranges that exceed three hundred feet in length.
The short antenna ranges have adjustable height source (transmit) antennas and track mounted test-antenna positioners permitting easy modification of transmit-antenna-to-test-antenna separation and polarization. The ranges are clear of reflection producing objects with the exception of the flat intervening ground. The ground reflections are normally controlled where possible by adjusting the test tower and transmit tower heights and separation distance depending on the directional characteristics of source and test antennas, as well as by judicious application of absorbing materials.
