Antenna 15m 21 MHz Links →
Dipolo rotativo per i 21 MHz
Realizzare un dipolo rotativo per i 21 MHz, partendo da un dipolo commerciale per i 14 MHz
Delta Quad
And an antenna of my tilting design with a winch 4 DELTA-QUAD elements for the 15m with 2 radiators supplied in phase opposition (180 °) and are spaced 1.77m apart
Dismantable Yagi for the bands 10-17m
Gain, SWR, Front/Back and Impedance for the full 450 KHz

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
