[80m] 4 square vertical array 3/8 wl.

Want to put up a 4 sq. of 3/8 wl. verticals (27 mtrs high) for several
obvious reasons like raising current maxima away from the lossy eath and
possibly later add a 160 configuration.

I plan to do a classic 1/4 spacing but I read in ON4UN low band dxing and an
article by W7EL about changes in phase relationship when using higher than
1/4 wl radiators. This apparently applies to 1/2 wl and 5/8 wl. radiators
but nothing is mentioned how it affects 3/8 wl !!

1. Now, I appreciate this fact, what I would like to know is - from a
practical point of view does EZnec version 3 and other modelling programs
compensate / take into account this fact ?

Otherwise assumptions for array performance can get really out of hand.

2. Have anyone tried in practice to phase 4 verticals of 3/8 wl. ?

Regards,

Henrik
