The AH-4 is similar to the SGC autocouplers, MFJ has a look-alike as does Array Solutions. The half- wave line repeats the high antenna impedance at the tuner. The tuner, matchbox or transmatch as it is sometimes called, will not correct the actual SWR condition on the feed line OR antenna, but it will resonate the antenna system as a whole that the radio "sees" on it's output and allows the transmitter to deliver as much power to the antenna system as possible within the design parameters of the tuner. The antenna pattern produced by phased array antennas depends on the nature of the elements, the spacing between them, and the ratio of the currents flowing in the elements. 416-667-1000.
