I used a normal Channel
7-11 television antenna mounted on a tripod. My apartment was on the 10th
floor of a huge apartment block in Täby, north of Stockholm. My balcony
faced south, making satellite observations easy. The antenna can be seen
below while tracking Skylab. I had to move the antenna three to four times
during pass to follow the spacecraft signal across the sky. The beamwidth
was that broad.
