A Very Useful Aerial Resource

Marcel ON5AU has released a further title in his Practical Antennas Series. Volume 2 concentrates on verticals and comes along with access to many modelled examples. The link to it is below. The same author has also published two other titles, Advanced Antenna Modeling and Radio Waves Propagation.

The latter may be of interest to radio amateurs, DXers and broadcasting enthusiasts alike.
