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

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


Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band

A simple SWR Meter is to be used at HF

A simple SWR Meter is to be used at HF An SWR meter provides information about how well matched is your antenna with the transmitter and how well power is being radiated
