T2FD squashed rhombic
Denominata anche T2FD Terminated Two Wire Folded Dipole Antenna, si tratta essenzialmente di un dipolo ripiegato, molto silenziosa

Building The Lazy H Antenna
The Lazy H is probably the most elementary form of curtain antennas. The lazy-H usually consists of two horizontally polarized doublet or dipole elements, although with some loss in earth reflection gain it can be oriented vertically as an "H"
Broadband Antennas
The advantages of a broadband antenna are obvi-ous—fewer adjustments during tune-up. For some of the new broadband transceivers andamplifiers, a broadband antenna means no tune-up at all
Carolina Windom antenna
Here is my home HF antenna. It is an off centre fed dipole, with 10 feet of vertical radiator. It needs no tuner on 40m, 20m and 10m
Cobwebb 10-12-15-17-20 meter Building The Antenna
This antenna, I made, not only covers 10-20m but tunes quite well to 40 and 80, has a reasonable swr at 6m! and a good swr from 120Mhz to over 150 Mhz
Diamond w8010 banden 80-40-20-15 en 10 meter
The antenna described here is known by different names. It is a combination of two dipoles that are shortened with coils and thus cover the tires 80-40-20-15 and 10 meters and yet still have a fairly small size

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
