guys, the only claims we are interested in a real life repeatable distances by 90% of the people with the same setup.
There is no point considering claims that cannot be repeated by anyone else.
if 1 in 100 is getting 1000 meters with no mods, then it's not the typical range, or there might be an unusual noise floor in that area
or the extender somehow has 3-4 times the output power as the normal one etc.
Only repeatable distances have any validity.
for example now I have 4-5 customers who bought the half sphere helix and they are claiming 2400-2500 ft not flying sideways but in FPV mode, and with easy aiming , the distance is replicated in all 4-5 cases than a person can be sure that if they spend the money for that item they can get similar results.
Same thing for the Parasitic helix, people are flying 3000-4000ft in fpv mode, 6000+ft flying sideways, but the lowest number is 3000 ft , so people can expect that.
What is the point of considering a 5$ whip one person claims they are getting 2000ft, another 10 people 1200 ft, another 20 people still only 600ft?
Than 600ft is the most likely you are going to get..
Just use your common sense.
