I am going to use a tranmisster and receiver that work on the 433 Mhz frequency to send a signal over a long distance. I will be using 12V so I can have a strong signal but I am not sure of how to make the antennas? The lenght of the wire is not really an issue for my intent but I would like the antenna to be as sturdy as possible so I am thinking about a helical antenna. I have copper wires of varying gauges I can use. I tried to do my research but couldnt come to a comprehensible result. any help would be appericiated!
