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

Antenna 40 Meter Links →
Dipolo rotativo a caricamento lineare per i 40m
40m 7.150MHz ed ha una larghezza di banda con ROS 1:1.5 di 150KHz, e' realizzato con due canne da pesca in VTR da 7 metri l'una 14 metri totali di dipolo
For 40m I am also working on a 40m 4 Square
Started building a new groundmounted 80m 4 square
Helically wound two element 40 mt yagi
The HW-40 is scaled down to 28 percentof full size
Noise reduction on 40m
Radiation from power lines, data lines and so on in the antenna, I tried to cut into this noise and for this I inserted two common mode inductors in the power line

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
Spiderbeam 10-15-20m E' una Yagi tribanda full-size leggera, fatta di tubi in vetroresina e filo
