Antenne G5RV
It is a multiband antenna which is similar to a center-fed or a Levy antenna of particular dimensions chosen to obtain a low impedance on frequencies close to 3.5 7 and 14 MHz
Coaxial fed multiband windom antenna
This simple multiband antenna works on all HF bands from 3.5 to 30 MHz, including WARC bands other than 10.1 MHz
Build a sturba curain antenna for hf bands
The Sterba Curtain, as designed is non resonant.There are a couple of bands where the swr will drop to 3:1
Inverted V for 17-20-30-40m
A 4-band 17-20-30-40m antenna that rolls up into an small Grundig antenna case

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
A simple SWR Meter is to be used at HF An SWR meter provides information about how well matched is your antenna with the transmitter and how well power is being radiated
