<P><FONT face=Tahoma>This small antenna can allow hams which lack space to
install an antenna for 40 meters. This project has been originally produced
by F6CYV. I’m going to test this antenna in the coming weeks. I will try to
setup this inside my balcony.</FONT></P>
<P><FONT face=Tahoma>According to his experience, using it form inside the
apartament, european singals are all very readable, he has worked over 150
countries.</FONT></P>
<P><FONT face=Tahoma>The antenna is made of 2mm wire.</FONT></P>
<P><FONT face=Tahoma>The 2 coils are constituted by 18 turns of 2 mm wire,
distance of tunrs is also 2 mm.</FONT></P>
<P><FONT face=Tahoma>The diametre of the coils is of 7,8 centimeters.</FONT></P>
<P><FONT face=Tahoma>The Feed of the dipole is done with a 75 ohms tv coaxial
cable.</FONT></P>
<P><FONT face=Tahoma>A 1/1 balun would be recommand for a correct feed of the
coaxial cable to the dipole.</FONT></P>
<P><FONT face=Tahoma>It is not necessary to use a coupler, it is enough to
set the length of both extremities of the dipole in order to have at 7.050 mhz a
low SWR, and especially to pay attention what the lenght of the 2 sides of the
dipole to be identical.</FONT><BR></P>
