Top feed linear loaded 80 m 3/4 wave


This is a vertically polarized Phased array. The left Vertical wire is 180 degrees out of phase with the middle and right Vertical wire. At 1/10 wavelength spacing from the right Vertical wire to the left Vertical wire it is producing a End-Fire Bidirectional Pattern,that developes a Gain of 5.9-DBi

Broadbanding half square antenna for 80mt
Half-square antenna is by naturerelatively narrow band.1On80 meters, for example, an SWR be-low 2:1 can be achieved anywhere in theband, but only over a relatively small range 60 to 100 kHz

Double bazooka/coaxial dipole antenna
A typical, dipole antenna has bandwidth of about 50 to 100 KHz

EWE rx antenna for 80 meter
The antenna is an aperiodic inverted U which is operated against ground.. Coupling to the coax to the rx is via a 1:3 transformer

Hex Array 80/40 Meter Vertical
Homebrew 80/40 meter trap vertical. The trap is a coaxial cable trap, made from RG-213 cable


Take off angle of horizontal antenna

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane
