I discuss a study I did to quantify the saltwater effect for vertical antennas on the saltwater shore. The results motivated me to choose St. Andrews State Park overlooking the Grand Lagoon for my RaDAR Rally venue. I likely will use the Alexloop magnetic loop, which is vertically polarized for my portable antenna. This was the topic for our October 23rd, 2023, Beginner's Academy Zoom meeting.
