Fosa 180° Rotating Dual Axes Stainless Steel Ham Radio Antenna Mount Bracket with Installation Bag - Perfect for Car, Truck, RV & Outdoor Radio Communication

I wasn’t sure about this because the pictures weren’t very good. They did not show it being attached to the window glass of any car and that’s exactly what it’s used for it has four really good Alan set screws and a nice piece of what appears to be stainless steel that goes behind the set screws and then it tightens onto the top edge of your window. It’s adjustable right left And I think it’s a pretty good deal instead of drilling holes in the rental car lol. I did shorten my antenna because I wasn’t sure at 85 miles an hour all that Leverage would be very good on the tempered glass passenger window so use common sense and don’t put too big of an antenna on it and too much strain on the glass if you’re going to go the speed limit.
