This stand is for an RCA HDTV multi-directional antenna. I designed it because my antenna gets a better signal when standing vertically, and I needed it to fit on my window sill without interfering with my blinds or my window opening. Hopefully this can help someone else as well! Here is the antenna for reference: http://www.amazon.com/RCA-ANT1650R-Digital-Amplified-Antenna/dp/B0027FGW3K If you like my designs, let me know with a little bitcoin: 16QaNzCAGKhyjAtwPhy9WxNk8NRhzw8rk7Print as-is with no support. I first used PLA but had warping issues as it's in the sun all day. ABS works just fine.
