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

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
A simple SWR Meter is to be used at HF An SWR meter provides information about how well matched is your antenna with the transmitter and how well power is being radiated
