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.

A BOG is an excellent choice when stealth is the driving requirement, otherwise
arrays of short verticals provide significantly superior performance compared
to BOG or short Beverage occupying the same physical space.

Hi Frank
Any particular reason you don't mentioned FLAG's, or EWE's?
Flags are easy to feed, they are broadband and have the same RDF directivity on
160,80,60,40 and very usable on 30m. 4 Phased Flags fit on 150ft and outperform
a pair of phased 1000ft long beverage. The vertical flag has a low take off
angle excellent for DX, 20 degree elevation lobe, and a beverage has 40 degree.
Also you can turn a Flag array in all directions and a beverage is fixed in one
direction, and when you decrease the frequency the front lob become so narrow
that makes useless on 40 and 30m.
Vertical arrays are mono band. You need one for 160 , another for 80, and if
you want 40 and 30 two more. Also they needs a lot of phasing cables and a
large real state area far from constructions.
What am I missing here?
Regards
JC
