Extremely Short Transmitting Antennas
There may be some environments where the dreaded antenna policy is so strict that you not dare put any short-wave antenna of usual dimensions outside

Linear-loaded-short-dipole-21mhz

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
