Practical Wire Antennas book. Published June 1st 1989 by Radio Society of Great Britain. Understanding antenna systems, measurements and radiation patterns was part of the evolutionary step in developing my knowledge within the hobby. This book turned out to provide all of the basic formula required for me to begin making antennas. I was in my mid-teens when I bought this.

Amateur radio: A 21st Century hobby. Amateur Radio: A World of Possibilities In many practical situations it is possible to operate the dipole satisfactorily without one, but there may be a slight increased. Amateur Radio: A World of Possibilities. GB1SS: schools speaking to Tim Peake. It is also possible to operate the antenna at a frequency where its length is three half-wavelengths, or any odd multiple of half-wavelengths long. This enables a dipole to be used on more than one band of frequencies. In many practical situations it is possible to operate the dipole satisfactorily without one, but there may be a slight increased risk of interference if one is not used. Simple baluns can be bought from antenna suppliers, or made. The maximum radiation from a dipole takes place in the centre.
Such antenna designs do not frequency scale easily. Antennas made of insulated wire cannot be analyzed by NEC-2, but NEC-4 and EZNEC Pro/4 work okay ¾ Twin lead folded dipole ¾ Twin lead J-pole ¾ Butternut radials.

Amateur radio frequency allocations. Amateur radio frequency allocation is done by national telecommunication authorities. Globally, the International Telecommunication Union (ITU) oversees how much radio spectrum is set aside for amateur radio transmissions. Individual amateur stations are free to use any frequency within authorized frequency ranges; authorized bands may vary by the class of the station license.
