I made my own 1/4 wave ground plane right after I got my technician license. I didn’t know if this was going to be my thing. I had an aluminum sailboard mast already in use for my hand made antenna. It worked well but after using the Arrow Yagi for APRS through the ISS and it working like a charm, I knew I was going to get the Arrow 1/4 wave. This one is the combo that ads in a 440 element.
Arrow makes really nice amateur radio antennas.
