Antennas

摘要

In the May 'Antennas' column, I discussed some aspects of mobile antennas and promised to give some information on magmounts, which use an antenna base with a magnet to fix the antenna to a horizontal flat surface of the ferrous metal vehicle body. They have the advantage of simplicity and require no special fixing arrangements, enabling them to be used with a vehicle on a temporary basis if necessary. The coax feeder is routed, either through the door seal (if you are using thin coax), or through a partly-opened window (if you are using thicker coax).
