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
Atu balanced feeder antenna system An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
