The feature series in the last three month’s of Q Bit has been about using 1/4 wave stubs for filters. To follow this up, the author is going to provide an overview of the theory and a short practical demonstration of stub filters.
Doug ZL2TAR has plenty of professional and practical experience with designing and implementing 1/4 wave filters to meet the requirements of closely located antennas and site that may suffer from interference.
If you like you can review the articles before you come along, and be armed with some good questions, or just come along and hear a complicated subject explained in a clear, simple but precise and correct manner.
