Been working on NVIS antennas for the OHQP this Sat but had a major
malfunction just when all antennas seemed ready to go.

Something I learned from an extensive modeling study about ten years ago is that the optimum height for an NVIS antenna is a quarter-wave. Higher reduces upward radiation, lower increases ground loss. This study was peer reviewed.
