My big vertical antenna project
The antenna project, specifically a DX-Engineering, Model DXE-MBVE-1, 43 foot mono pole vertical antenna

Progetto antenna verticale 10-20-40
Nel nostro caso uno stilo di poco piu' di 9,5 metri con un adattatore di impedenza alla base,puo' funzionare su tutte le bande HF dai 10 agli 80mt

Phasing short hf vertical antennas
The initial 40 meter phased array consists of two 10 foot high elements spaced one-half wave length apart


Take off angle of horizontal antenna

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane

A remote antenna switch
