Switchable Antenna 80/160
The idea to work this interesting band was to use an arm of the dipole and the vertical part of the feeder cable that together forms an L antenna

Antenna 80 meter Links →
Antenna GP 3,5 MHz a carico lineare
This vertical antenna for 80 meters at linear load, of 1/2 wave is born from the need to have a good angle of radiation
Antenna HF multibanda deltaloop 6-160 metri
We can choose between loop-magnetic and DELTA LOOP, the latter does not require great skills and particularly high manual skills to build it
Antena para 80/40 metros, bobinada e de alta performance
Antenna for 80/40 meters, traps and high performance
2-element Parasitic Vertical Array for 80
this article I want to look further at radial topology of vertical arrays for the low bands

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
