Antenna 40 Meter Links →
Adding 30 and 40 meters to the 4 Element SteppIR
The first thing I did was to extend the fiberglass tubes to the 213 inch length specified
Antena multibanda G5RV
This is an adaptation of the antenna of reduced size to 80 and 40 meters, whose operation was a success.
Balanced Terminated Folded Dipole
Designed my btfd to operate on a minimum frequency of 1.8 mhz with an intended use spaning from 1.9 to 11.0 mhz

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
