Quad antenna project
The Quad should be fed individually with 50 Ohm coax cable per band, of course with a relay box on the boom

Quad or loop antenna
The feedpoint of a full wave length 1 × λ loop or cubical quad QQ has an characteristic impedance of approximately 115 Ω
The Compact Quad Multiband HF Antenna
The resulting design is a loop that is elec-trically 1 λ in the 20 meter band, fed by a matching section with a Z0 of about 800 Ωthat is λ/2 long in the 20 meter band
I started working with the half square antenna afew years ago and have one on 30M and another for 20M. They work very well for being so low
Quad 30 40 meter
I was able to work short path to EU, JA quite easily on 40m and 30m alike
