What do you call a directional antenna that is a full wave loop on 6 meters

The basic hentenna appears to be a rectangle of some 40 X 14 inches, it can be built with wire and pv

Showing the current distribution on the aerial, the second one the directional diagrams

It is a strange antenna and it is an asymmetrical double rectangle ADR loop antenna

In questa stessa sezione è descritta un'altra antenna per i 50 MHz

È una antennina che occupa pochi cm ideale per un pò di traffico in banda UHF

Hentenna unidirezionale per 14 MHz

The basic function of the hentenna structure is the 1,50-λ-extended-quad, this antenna with the figure of an oblong has a gain of 3,6 dbd

No special parts are required. you can useany electrical conductor to make the main rectangle,broad adjustment wide bandwidth

The array has two one-sixth wave radiators separated vertically by a half wavelength

Si tratta di un loop con i lati lunghi 1/2 λ per 1/6 λ, alla base

It must be supported by an insulating material, here 2 meters of 32 mm PVC sanitary tubing, nested in a section of aluminum tubing
