I have used 8 foot weather balloons, five foot rubber balloons, and Mylar balloons. The discharge device is a bleeder resistor to the antenna's ground, high enough wattage non-inductive to discharge the static buildup at an adequate rate while preserving the electrical characteristics of the antenna. So if molecular elements like O2 and N2, that are many times the size of helium He can do that, you can imagine how helium would act. Do not fly your kite or balloon near power lines of any description. My name is Bob, and my activity on Top Band goes back almost 30 years.
The weather balloons stay up all night, but really lose size after about five hours. The five footers stay up about ten hours, but they are getting pretty sagged by then. Note on a potential hazard. Some amateurs in the past have used hydrogen to lift balloon antennas. As a ham, you've probably wondered how to get a "sky hook" to hold up your antenna. Lighter-than-air balloons are one solution - for temporary installations in calm conditions.

This will be the antenna used when conditions permit - weather mostly the limiting factor.
First of all, you should be concerned about potential shock hazards and high noise levels resulting from wind-induced static. The solution at low power levels is free fucking drawfs midgets here. The discharge device is a bleeder resistor to the antenna's ground, high enough wattage non-inductive to discharge the static buildup at an adequate balloons for amateur radio antenna while preserving the electrical characteristics of the antenna. Ten watt resistors will handle about watts of RF. An inductor can be substituted for the balloons for amateur radio antenna, the value depends on frequency. It will must act as an RF choke at the frequency of operation but a DC path to ground for static electricity. Another way is to do it by making a spark gap, shown in the illustration to the right.
