I installed these on my 2005 F150 fairly easily. I'm tired of my standard antenna banging against the garage roof every time I drive in. Installation was very easy, just screw on and off and you're done. Different screw kits are supplied for different brands and models. I couldn't tell any difference in radio reception. The only issue I had, which may have been more user error, was that the packaging said "Sword Antenna" in large letters, it's clearly a sword and nothing else. I thought it was a more subtle design since the description says "Short Antenna Replacement" and doesn't mention a sword.
