Moxon Rectangles for 17-20 Meter

Antenna 24 mhz 12 meters Links

17



Basic Beams for 12 and 17 Meters
Monoband Beams for 12 and 17 MetersI designed a pair of driver-director Yagis for 12 and 17 metersusing antenna-modeling software

Dualband-Beam 12/17 m
The beam has only one feedpoint with 50 Ohm

18/24 MHz rotatable dipole
dipole to cover the 18 and 24 MHz bands it by a rotatable dipole that I could install above the Yagi
