Bernard ZL2BD talks on small magnetic loop antennas

Published by ZL2HD -

Bernard presented on small magnetic loop antennas at the June meeting.  Bernard has been working on these for many years, and the main message was -They work very well but must be made very carefully and you need to accept a number of limitations.

The main limitation is the very small bandwidth, followed by the high level of care required in designing and making them.  A key issue is loop resistance. Bernard makes his loops from 1 inch copper pipe and to reduce the resistance from the joins, uses 4 x 90 deg angles, carefully silver soldered. His loop is a square!

June 2019 Main Meeting - Loop Antennas with Bernard ZL2BD

Published by ZL2HD -

Bernard is well known for his work with HF loop antennas and has many years of designing, building and evaluating these interesting (and somewhat rare) variant.

 Bernard's recent talks at other local branches have had very good reviews and some members asked if he could speak at our monthly meeting, which Bernard has offered.  This was also following a loop building session at his QTH where models were build and tested.

Please come along on Thursday 27 June to hear Bernard's talk.  

 

March Meeting - 1/4 Wave Stub Filters

Published by VHFAdmin -

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.
