Dipolo bobinada 40-80 Mts
This dipole for 40 and 80 Mts band. With coils, it is an excellent project -archi tested- in a band of 40 Mts. It has the same behavior of a dipole of 1/2 normal wave, and in 80 Mts band
Inverted L Antenna 160 -80 -40 meters
Vertical Inverted L for the 160, 80 and 40- meter Bands
Double-L Antenna For 80/160
This 10 - 160 meter tuned horizontal loop antenna is fed with 450 ohm
Larga banda in 80mt

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
