If you attended today’s Lecture and Lab, I hope you had fun! If you need a copy of Budd’s original Buddipole plans, you can find them here. My add-on page of changes is available in this file. Some of you also had questions about the choke balun that I use.

Our next club meeting will be on September 5th. NWS radar expert Jason Dunn will present on “Reading Weather Radar.”

Conditions would not have improved much during the first seven years!
