Antenna for 40m
The installation of my half-wave antenna for the 40m band. The tuning system is installed at the top of the attic
Capacitive Antennas 7.050 - 3.550 MHz
The capacitive antenna is a very space-saving antenna with good receivings caracteristics for the interior also for sending with 100 Watts
Dipolo para 40 80 metros
This dipole antenna for the 40 and 80 meter bands has good performance and is simple to build
Dipolo rotativo para hf
When it comes to dipoles, we wonder how efficient
Antenne verticale monobande 7Mhz
