Coaxial-Antenner - 1,79 meter for 27 MHz
A 2 mm wire 1.79 meters long by 27 MHz. This antenna whip is shortened with an antenna coil. The coil of the antenna must have a diameter of 17 mm and have 17 turns that must be wrapped tightly against each other
Delta loop de 26-30 MHz 10-11m
a vertical polarization antenna ,with high efficiency and as small as possible
Flat eh antenna from 18 to 28 MHz BAND, UA1ACO
The antenna is fastened onto a wooden or plastic former to ensure that the operator ts head-body does not influence any antenna parameters
Ground CB antenna, OK1IKE
Antenna, shown in the picture, is characterized by simplicity and easy realizability, it occupies a minimum area of height slightly over 1.5 meters

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
