80-75 Meter 4-Square Array
- The SWR from 3.5 to 3.9 is below 1.5:1, the F/R of the array is 20dB average and with some signals even better

Single Support Gain Antennasfor 80 and 160 Meters
On 80 and 160 meters an antenna withmodest gain and good front-to-back (F/B) ratio, along with a steerable pattern,can be very effective for contesting
The 80 Meter Inverted Vee
The 80 meter inverted vee is a common and classic antenna. Like all inverted vees, it requires a single center support
Tower for 80mt 3.650 et 3.780 Khz
Tower tuned on 80m, the terminal capa is 16m high and has a diameter of 2.4m
Un dipolo per le bande basse
Il dipolo e' un classico trappolato, ma va meglio di quelli commerciali che ho provato, costa moltomeno e leva lo sfizio di farselo da se'
160m/80m dual band vertical
This vertical is a good compromise when you want good performance on these two low ham bands
