Antenna multibands
The whole is easily tuned, with an ros of less than 1.5 on all the bands between 10 and 28 mhz. the results in dx are very good, the starting angles

Building short trap dipole
a QST article for a short 40, 80 and 160 meter trap dipole, I decided to pursue construction of this antenna, and bend the 160 meter end wire, if necessary to fit into the yard
Antena para 40 e 80 metros tipo W3DZZ
This antenna is equivalent to a simple dipole in 40 meters, since the traps are equivalent to an insulator
Three Double-Extended Zepps
The antenna can also be powered with a 300 ohm TV two-wire line, but it is preferable that the power supply is via a stub
Windom
Adattare l'impedenza della discesa a 50 ohm con il valore tipico di questa antenna, che sia aggira intorno ai 300 ohm
Dual band Antenna 80/40 loaded coil inverted V
Antenna 40-80m, inverter "V" SWR results are quite good at 3.799
