Dipolo orientable con carga central para 7 Mhz
This was set at the frequencies of 7.1 MHz and 3,650 MHz, but it can be adjusted for the portion of band that you want
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
