John Jacobs, host of the Field Radio Podcast, returns join in a discussion of basic DIY HF antennas.  We talk some of the most common and easiest to build antennas such as Dipoles as well as how to build them and where to scrounge for materials!  We also talk about our plans for our respective shows in light of Cale’s recent archiving of Ham Radio 360. We share the details of the Digilent Analog Discovery 2 package (and discount code!) with the audience!
