[TowerTalk] Nested 4-Squares

[Mike Smith VE9AA]

I have 2 partially nested 4 squares and also a 2el array, all in a patch of
uneven woods roughly 65' x 135'

 

2el 160m runs along West side of the rectangle.

 

The 80m array is roughly in the center of the rectangle

 

The 40m array is on the far NW corner of the 80m array, with the NW 40m
element just barely outside the NW element of the 80m array.

 

I have taken dB measurements with my antenna analyzer as the 'transmitter'
and my rig as the RX and things

appear quite normal.

 

At most (and it's hard to quantify as there is external clutter in the NW
direction on my property) there

is a slight aberration in the NW direction on 80m.  

 

Mike VE9AA...wire 4 squares, hung in trees, 2 raised radial per element.  I
posted my readings on this very reflector a year or so ago with all the
readings etc.

 

Good luck !

Is nesting 4-Square arrays a good idea? By that I mean, for instance, an 80m

4-square inside a 160m 4-square. I was about to model this but it occurs to

me that someone has probably already done this exercise.

 

Good idea or bad idea?
