Active Kortbølge antenna
This is an active antenna for shortwave frequencies between 7.5 and 30 MHz (40 meters to 10 meters). The antenna is made of a copper wire 4 mm in diameter and has an area of 0.05 square meters
Am small loop antennas
Reception of AM radio stations found in the range of frequencies between 550 and 1700 Khz. Some AM DX listeners consider the loop superior to outside

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
