Edmund A. Laport was Chief Engineer of RCA International Division Radio
Corporaation of America, and is the author of "Radio Antenna
Engineering".

On page 336 of "Radio Antenna Engineering" Ed gives the gain of a
two-layer tiered rhombic as 14.7 dBd.

On page 528 of Arnold B. Bailey`s "TV and Other Receiving Antennas" is
given the gain of a single-layer "horizontal" rhombic in free-space
which has a dide length of about 3.7 wavelengths. It has a gain of about
14.5 dBd.

I`ve used Laport`s criteria in rhombic design and been satisfied.
