Indoor antenna for 7 mhz

Antenna 40 Meter Links

73



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
