With this antenna I reached a range of 2.5 kilometers with a cheap video transmitter (The radio range was over so I could not go on) I used the calculator from this site: https://jcoppens.com/ant/helix/calc.en.php the reflector is 32.4 mm copper board I used a 1.2mm copper wire for the helix,but It is recommended to use 1 mm wire. second test 3.7km : https://youtu.be/20Nf8Qif4GU
