EZNEC says that the shorty-40 at 90 feet should kill the vertical and
the four square. The only angle where the four square has more gain is
at 41 to 56 degrees elevation where the shorty-40 has a null. You
should be seeing something like 12 dB difference between your vertical
and the shorty-40 for DX signals, in favor of the shorty-40. Sounds
like you have something wrong with your shorty-40.
