Shorten Dipole
A shorten Dual-Band Dipole with overall length of about 11 m. For this antenna I do not use traps but simple inductors, in order to cover the 10 & 40 m. Bands

Windom Antenna
The peculiar aspect of the I7SWX windom is the balun,wound on a simple ferrite rod,instead of the commonly used toroid
Morgain per i 40 e gli 80 metri
This antenna has in its main characteristic, the fact that with only 20 mtof space occupied it works the 80 meters
The Homebrew Buddipole 17m/15m
I made the Buddistick first, then later made the Buddipole. Both are easy to make and work well
Doublet Antenna
The ATU design gives a reasonable 'Q' factor so you will have to tune it regularly. Eurotherm PID controllers and a stepper-motor can make a good auto-ATU
The Dipole antenna
The DIPOLE antenna, here some reference data, pointers and ideas that may help you

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
