Invisible DX Antenna for the Low Bands


This paper describes a multi-band DX antenna for the 160m-40m amateur radio bands with low visibility but great performance for long distance communication

Linear Loaded Wire Antennas
I have done a lot of research on wire antennas on the internet as well as other places and developed aninterest in linear loading

Loop Antenna Info
I have personally used a 160 meter band Horizontal Full Wave Loop antenna with very good success. I worked all 50 states and several countries with 100 Watts

Polarized antenna the Linear loaded
This is a vertically and horizontally polarized antenna the Linear loaded 1/4 wave length vertical radiator introduces very little loss

Topband with its wavelenght 160m
Dimensons are explained on the picture. During my initial testing was resonance on 1850kHz


Linear-loaded-short-dipole-21mhz

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
