Robert Swanson's photos with the keyword: field day

In this photo, the tower is now up. In addition to the horizontal elements, the tower was constructed with a pulley system. An additional horizontal wire dipole is being raised using that pulley. This antenna system was used during the Field Day (28 June 2025) for many contacts. Our amateur radio (HAM) club is closely involved with the city Public Safety organization. Events like this are practice for handling potential natural disasters. WØZWY, Sioux Falls, South Dakota. Image taken with the phone and processed with GIMP.

Our amateur radio club (HAMS) took part in the official Field Day 28 June 2025. One of the members has built a tower that can be towed behind a vehicle. WØZWY, Sioux Falls, South Dakota. Erecting the tower is specialized work, so we just stood aside, unless asked for help. The team here has done this several times over the years. You can see the antenna arms pre-positioned on the ground, before being mounted on the rotator at the top. Image taken with phone and processed with GIMP.
