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

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
