1/4 Slopers 40/15M Band
The antenna that most suited this application was a 40m band sloper as the guy wire to be used was slightly longer than a 1/4 wave length at 7 MHz and the top fed sloper was the most convenient installation having the least impact

Vertical Dipole
All radiators are 1/4 wavelength radials for individual bands are 5%
Wire antennas for the low bands
I have experimented with a variety of wire antennas. Any configurations have to fit in my 100ft long by 40ft wide garden

15-40-80mt Dipole
I have this balun installed on all my coax feeders

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
