Better than what? Stock? Probably as good as stock. At least close. But it's hard for me to tell living in the middle of a city. I can pick up stations with out a antenna.
What did you solder the antenna coil to the head of the screw? Im trying to solder it together but it wont stick to the head of the screw. help please!!!!
I had the same issue, I was using a battery powered soldering iron that was garbage. I finally got it to stick when I used the soldering iron to heat up the bolt, putting the solder on a cool bolt causes it to instantly harden and not stick.
