HF Magnetic Loop Antennas - Dr. Philip King VK2JPK - Manly-Warringah Radio Society lecture

The Manly-Warringah Radio Society (http://www.mwrs.org.au) at Terrey Hills in Sydney, Australia, holds lectures on the third Wednesday of every month, except December.

In this February 2020 lecture, Dr. Philip King VK2JPK share his experience with magnetic loop antennas. For many of us, apartment living seems like the kiss of death, at least as far as HF operations are concerned. But the challenges of poor earths, uncooperative Body Corporates / Home Owner Associations, lack of space etc. can be overcome, as Phil demonstrates here.
