Built by shaping conductive wire into a closed loop, these antennas operate by interacting with the electromagnetic fields around them. In a RTTY contest, the Band is full of big signals and lots of noise. A quad is a Yagi–Uda antenna ("Yagi") made from loop elements instead of dipoles: It consists of a driven element and one or more parasitic elements; however in a quad, each of the loop elements may be square, round, or some other shape. The loop is very quiet because of its radial directivity, and so has some gain, therefore rejecting some of the noise otherwise received by an end-fed or dipole antenna. 8/2. 2) Horizontal DELTA LOOP: built by Lucas, KN4MEJ 3) Horizontal DELTA LOOP: built by Leslie, VE9ASN DISCLAIMER: I have not personally built or used any of my these three antenna described here.
