Moxon-Principles Dualband-Moxon 10+6 m Moxons 10-15 m Wire-Moxon 17 + 20 m 2-m-Moxon

The Dualband-Moxon-Beam for 17 m and 20 m

Nested Moxon with wires and one feedpoint.

 17 m 3 dBd, 20 m 3,6 dBd

The antenna is fed with 50-Ohm-coax in the middle part of the 17-m-radiator (wire 10).  The 20-m-radiator (wire 2) is connected with a transmission line. This transmission line is made of 75-Ohm-foam coax (V=0,82).
