“The Quad Antenna uses a single, central-fed frame with a feeder-line. Therefore you must use an ATU for operating this antenna. Excellent would be a “Z-Match”, a 1-KW-Tuner will be described on another page.
The reflector has one loop for each band, self-resonant without stubs.
The first DK7ZB-Quad was introduced in 1995 and contented a mistake and had not the best performance. In 2000 the Quad was optimized for 1-Lambda reflector loops with “EZNEC” by W7EL.
