Okay so from what im seeing is take extreme caution when using these question though is why aren't they regulated on the websites or the sale of them even prohibited.
It’s virtually impossible to control foreign manufacturing and import. Just look at the illegal drug trade as an example. We also run into an issue between legal to own versus illegal to use. Then we have the situation as to what is legal for licensed HAM operators may not be legal for common consumer users. In that situation it’s a qualification issue, very similar to what occurs in firearms with full auto weapons and suppressors.
There are many areas in life where because we can does not mean we should. As federal aviation law states it’s not legal to fly BLOS there’s nothing we can buy to increase range that alters that. Properly oriented with proper body positioning while avoiding structure or foliage obstruction of the RF signal, the stock antennas are quite effective out to a couple thousand feet, far enough to exceed effective control LOS.
