The new look in antennas is here. Soon VHF log-periodic antennas will l gt e replacing vagi arrays of practically ail types, and also replacing old standbys such as the collinear, helix, and corner reflector. This revolution has already been taking place in the television antenna business for several years...

Vhf Success Stdry

In the limited field of Amateur Radio we seldom see early evidence of a stunning success* The so-called classics usually take several years to develop. Swan's six meter side band transceiver is a classic now, scarcely 12 months from the date of its first commercial release. This is all the more remarkable because of the smaller number of hams occupying six meters, as compared with the lower bands* and startling* too, because there are so many neophytes on six meters holding technician licenses...

Designing Permeability Tuned Coils

If you have trouble designing slug-tuned coils for your construction projects, here is an approach that is simple and almost foolproof. It even shows you how to use those old slug-tuned forms that you have in the junk box. Within the last decade, the development of improved ferrite core materials, stemming from basic research into the nature of magnetic materials, has brought about a quiet revolution in the art of coil design. Inductors wound on powdered iron require fewer turns of wire for a...
