By band how much outside teh normal 40 channel band are you expecting
to operate?
I used a single loop on 6 meters and got about 600KHz bandwidth with
good results. A single loop is rather easy to build and rather cheap.
There are more pronounced nulls off the quad loop compared to a
dipole. Also th efeed impedance is about 100 Ohms so a simple quarter
wave section of 75 Ohm cable will be all that is needed to match the
antenna.
