Switchable Antenna 80/160
A lot of radials, metallic railing, ground leak point, idraulic pipes are useful.19,5 m. of 1/2 dipole and about 7 meter of the feeder cable vertical portion, aren't enough to tune the antenna on 160 m
Quad cubical 80 mts
Cubical Quad antenna for 80 mts. Given that the working width in this band is very wide, the calculation is in Freq. 3,740 Mhz. and I will place the formula to calculate it according to the work preference of each one
Quarter wave 80 meter vertical antenna
In the summer of 2010, I decided to construct a 1/4 wave 80 meter vertical using 3" OD Aluminum Tubing. The large diameter yields broadbanded coverage of the 80 Meter Band. It's an 1/8 wave vertical on 160 meters also
Building 80-meter 4-square
my 80-meter 4-square it will consist of 4 wire verticals
