Hi Art,

While this was the common theory many years ago, there other ways to get
gain from an antenna other than boom length and number of elements.

ie On 2m we are able to get 11.2 dBd on a 45inch boom with 3 elements
stacked 2 wide. Yes, this is range tested see results at

My ARRL books go back a decade or more
and the graph showing gain per boom length
has several curves based on different measurements
e.t.c. Has a graph been made based solely on NEC
program findings over say a perfect ground and at a uniform height?
