[NJARC] Antenna Physics

[Pete Malvasi]

However there is a very unique factor with "wave" antennas which are not associated with a more common tuned antenna and that is the wave tilt is formed by the velocity factor difference in the wire to the earth closely spaced beneath it. That is not an effect which is in play with a more typical antenna. The wave angle of those are formed by reflection from ground and the pattern from the array configuration.  So Beverages studies were quite valuable but also quite unique to the "wave" antenna.

Hi Joe, Alex, and antenna freaks everywhere,

The fellows at RCA and GE, Alexanderson, Beverage, Chester Rice, Edward Kellog et al, understood the physics of antenna wave angle quite well.  If you check out their paper, "The Wave Antenna, A New Type of Highly Directive Antenna" Trans. AIEE Vol. 42 pp. 215-266 1923 you can see that the antenna physics art was quite well developed at that time.  There is also a bibliography of 100-plus sources on earlier work on antennas.
