Antena for 40 and 80 meters type W3DZZ
I had a dipole for 40 meters in inverted V, with twice 10.25 meters of 2.5 mm2 copper wire in section. I decided to transform it into a W3DZZ to be able to work also in 80 meters

A Co-ax Trap Dipole For 40, 30 and 20 Meters
Another way to minimise the loss of an antenna using coax traps is to use the minimum length of coax needed to achieve resonance
Antena morgain 40/80M
This antenna reduced dimensions for 80 and 40 Meters
Antena dipolo Multibanda
This dipole antenna functions as a half wave dipole in the 40 and 20m bands. In the 80m band it is a shortened dipole and in the 15m band it is a 3/4 wave dipole when the 40m 7Mhz thread resonates at 15m 21MHz
Antenna tipo G5RV
L'antenna e' alimentabile anche con linea bifilare TV da 300 ohm, ma e' preferibile che l'alimentazione avvenga per il tramite uno stub in linea aperta
El Dipolo G5RV
The G5RV antenna is expected to be the most popular among fans. Maybe because of the characteristic of being able to work in different bands

Noise suppression with X-phase II This device similar devices are known as QRM eliminators or noise killers, makes it possible
The K9AY loop antenna for 160 and 80m bands You don't have the space to put up a 4 beverage antenna's, an ewe or a 4-square and want 'good ears' on 160 and 80m? no problems try a k9ay loop antenna
