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

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

Lets build an 80 meter 4 square
Each vertical is 65 feet high. I also have a 20 meter 4 square insde of these verticals with another 4,100 feet of radial wires, plus another 5,280 feet of radials for a 160 meter vertical and another 2,050 L/F for the 40 meter verticals to the south, all radials are tied together with a total of 34,928 L/F of radials

my 80-meter 4-square it will consist of 4 wire verticals
