First let me apologize if you get this e-mail twice as I have been having
problems with MSN.com.
Hi JC,
Not all vertical arrays are mono band. A well built 4-square on a 60 foot
per side can do a stellar job on 160, 80, and 40 meters while extending well
down into the broadcast band. The 3 element as well as the 4-square based 8
element on an 85 foot diameter circle will do the same thing.

Far from it ... the YCCC "9 circle" is a phased array receiving antenna that
covers 160-40 meters in a 120' diameter circle (45 degree increments). The
5 element square (90 degree increments) fits in an
85 foot square.
RDF of the YCCC array is comparable to that of a .625 x 1.25 wavelength BSEF
array on 160 meters in about 1/8 the area. The 80 meter RDF of the YCCC
array is comparable to a 1.5 wavelength (1000') Beverage.
See Sept/Oct and Nov/Dec 2011 issues of NCJ.
