The Flying Antenna. Post 2158.
If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=-VWBUDJv2n0 Radio amateurs have used all kinds of objects to support their HF/VHF/UHF antennas--including in this case a helium filled balloon. According to the video's producers, Glenn (N6GN) and John (K6PZB), results were excellent during the brief test with an approximate 40 dB signal improvement over previous antennas. Here are some of their comments: " helium balloon supported antenna tethered and fed by a surface wave transmission line provides more than 40 dB increase in signal strength of amateur radio communications. This is essentially the same presentation given by N6GN at ARRL Pacificon in October 2011. Related SWTL projects & theory in ARRL QEX May, July, November 2012.
