The open wire feedline multiband antenn
Multiband antenna fed with true open wire feedline -sometimes known as tuned feeders seems to have been forgotten by many

Antenna Multibands Links →
Dickerdipol antenna multibands with balun
The 5 radiating wires are spread to 1.2 m. with un balun 1:4
Dipolo acortado
The calculation of the linear load is made by adding 30% to 30% removed from the irradiator, the dimensions being as follows, Total length of the irradiator: 5, 51 meters Length of each linear load: 1.54 meters
Dipolo HF 80m - 60m - 30m
Ho deciso di costruire un dipolo che mi permettesse di operare sulle gamme 80m-60m e 30m
G5RV antenna 40/10 & 80m - 40-10m
I bracci terminali possono essere istallati o paralleli al terreno oppure a v invertita

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
