Antenna verticale
Ho avvolto sulla canna circa 120 spire di cavo elettrico da 1 mm2, e ho collegato una estremita' dell'avvolgimento al centrale del PL

My 160 meter antenna is an Inverted L
My 160 meter antenna is an Inverted L. The length of wire required at 1.835 MHz is approximately 127 feet
Multiband wire vertical
When 3 bands are used a center pole and 2 wires on the sides are used. The center wire will always be the lowest band and to the sides the other two or four bands
Multiband vertical HF antenna
The antennas may be installed at height near one meter above the ground. Resonance counterpoises should be used at this placement
New Shortened Vertical for 17-20-30-40 Meters
a 4-band, 20' vertical half wave that uses two loading coils with taps. The results appear promising
Shortened 160 meter vertical
Highly effective for 160-meter DX and local work, easy to build and adjust, very economical
