... The advantage of a physical height (antenna length) between 180 and 215 degrees (see previous post regarding the magic number being around 195 degrees) is improved take-off angle and reduced skywave-groundwave interaction, not dramatic nearfield voltage increases. As I previously stated, works nicely on paper/software; in real life, I have not been able to construct an antenna which demonstrates an advantage to justify the difficulty of dealing with the extra length. Now, a 2m on down, why not "toss it on", just in case? Now, when loading a 1/4 wave physical length antenna to a 1/2 wave electrical length, I DO see an advantage, increased radiation resistance, minimal counterpoise required, etc. Even when taking into consideration the losses added by the coil ...
