Vertical 40mt no coils

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

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
