More on Wire, if you are interested in digging further. *BVARC Beacon -- The Radio Hotel -- Nov 2016 "The Skinny on Wire"* * March 2020 "Wire Simply Wire"*
Also, read two Rudy Severns (N6LF) articles about wire: Google -- *“Antenna Foil Conductors” and “HF Wire Conductors”.* and Google *"Georgia Copper"* all about copper radio products -- excellent. For Aluminum info read the *BVARC Beacon Feb 2020 "Working with Aluminum".* It is good to see the membership discussing the various and necessary antenna topics that have been discussed since the beginning of "ham time". Nothing better than knowing the technical background to support your on air efforts. Tnx for the discussion....73....Rick -- W5RH On Sat, Apr 30, 2022 at 10:37 AM john Parmalee via BVARC <[email protected]> wrote: > I missed the discussion but here is a factor.
