Los dipolos
The dipoles are generally half wavelength antennas, these are calculated using the following formula: Total dipole length = 142.5 / F (MHz)

Magnetic Loop Antenna Theory
The loops shown are all coupled with a ferrite transformer which is used to match the 50 ohms coaxial

Micro Controller Projects
On this web site you will find a series of projects of interest to Radio Amateurs and other hobbyists

Open line
It is often thought that running an open line through a wall is difficult

Rhombic antennas
The highest development of the long-wire antenna is the RHOMBIC ANTENNA It consists of four conductors joined to form a rhombus, or diamond shape
