Quad cubical 80 m
Quad cubic antenna for 80 meters, since the working width in this band is very wide, the calculation is in Frequency. 3,740 MHz

Antenna 80 meter Links →
80m Band Top using 2 elevated radials
The TLV80 antenna is mounted on a Fiberglas Teleskop Mast Height of mast is 8 meters
80 m 3/4 wave LLV
The left Vertical wire is 180 degrees out of phase with the middle and right Vertical wire
Dipolo rotativo delta para 80 metros
The rotating dipole for 80 meters has a length of 20 meters, its weight reaches 20kg
The 80m 2el. Yagi project
Tube parts on the ground. 10m long, 90 mm OD Aluminium pipe boom and the elements
The triple 4-square project antenna
The 40m 4-square will be centered in the 80m one, which will be centered in the 160m 4-square. hence the triple 4-square

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
