A 90 foot Irrigation Tubing Vertical

For the past couple of years I have been experimenting with making vertical antennas out of aluminum irrigation tubing

A Modified Petlowany Antenna
It is essentially a very short dipole with spiral-wound coils at each end

Antena vertical
Outside of the wave traps there is nothing difficult in the construction of this antenna; the traps are of homemade construction and we will use a simple ingenuity to make them

Vertikal Dipole 10-40m
The modelled inverted-V antenna is full size and will have a higher efficiency than a shortened horizontal dipole. If we consider a full size 1/4 wavelength

Verticale con circuito risonante alla base dai 160-ai 10mt
the self-construction of a vertical machine operating in the amateur radio bands, mainly from 160 to 40 meters
