Topband: VE3DO Loop

[K9AY]

...(we probably all know) elongated loops are not really loops in function. They are really phased verticals, and the horizontal part or component of the conductors is simply a phasing line. K9AY's, Flags, Pennants, EWE's, and other forms of elongated loops are really all just phased verticals in function.

Not so. Time to put this misconception to rest.

Read my description of K9AY Loop operation in the most recent ARRL Antenna Book and review the description of a DF loop with sense antenna in that, or earlier antenna books. 

I have never been able to achieve the same pattern as the loop using close-spaced elements in a phased array. However, a model using a small loop in combination with a nearby short vertical does indeed result in the same pattern. (Feed them with equal currents and 90 deg. phase shift.)

Magnetic lines of force from an arriving wavefront MUST induce currents in a loop. You can't ignore them and assume that the vertical end portions are the only place energy is captured.
