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

Antenna Multibands Links

166



Antenne doublet raccourci
On the low bands the half-wave doublet has a span often incompatible with the space available to deploy it

Antenne G5RV
It is a multiband antenna which is similar to a center-fed or a Levy antenna of particular dimensions chosen to obtain a low impedance on frequencies close to 3.5 7 and 14 MHz

Antennes Levy et center-fed multibande
Here are two antennas whose functioning is similar: this time we consider not only the length of the radiating element but also that of the two-wire line

Coaxial fed multiband windom antenna
This simple multiband antenna works on all HF bands from 3.5 to 30 MHz, including WARC bands other than 10.1 MHz

Build a sturba curain antenna for hf bands
The Sterba Curtain, as designed is non resonant.There are a couple of bands where the swr will drop to 3:1
