Topband: Array of MiniWhips?

[VE6WZ_Steve]

Hello Ash,

The small vertical (HI-z) arrays like the 8 circle and 9 circle depend on VERY accurate phase and amplitude between elements.
Even small variation in amplitude, or phase can destroy the pattern and RDF which is what makes these arrays effective.

The HI-z amplifiers used in these arrays have very accurate phase and amplitude which is normalized between all units.
I do not know what the PA0RDT amps are like, but this is a crucial thing you need to look at.
