Antenna helix 432-435-Mhz
Building a 14 turn home-made helical antenna for 432/435mhz

Two Small Helical Antennas for 2 Meter
The two turn 2 meter base-station λ/2 helix. Height is 6 inches, diameter is 6 inches

.htm The Gain of the Axial-Mode Helix Antenna
The axial-mode helix antenna, first described by Kraus in 1947, is probably the most widely used circularly-polarized antenna, either in space or on the ground


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

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
