Antenna 40 Meter Links →
Dipolo rotativo per i 40 mt a carico lineare
La lunghezza complessiva puo' essere ridotta fino al 40% della dimensione originale quarto d'onda senza le perdite risultanti dall'utilizzo di una bobina di carico
Electrically short dipole antenna for the 40m band
An antenna whose electrical conductor is much smaller than half the operating wavelength is an electrically short antenna
Multi Band cage Dipole Antenna Project
By efficient we mean an antenna that will radiate 90% or more of the energy output from the transmitter/amplifier, without a tuner
Prototipo di antenna per i 7MHz in 22cm
Prototipo di antenna per i 7MHz di dimensioni maggiori alla precedente, 22cm di diametro
Quad cubical 40 mts
This full size Quad-cubical antenna of an element for the 40 Mts band. It is a very good antenna, both in transmission and reception, it is built with copper wire
