Query: Not my first choice.

We purchased this item for our XM portable. It held up fine for about 6 months.PROS: The antenna did function nominally (all the time and in any direction) when placed at the apex of the base of the front windshield.CONS: Mounting clips: The flimsy plastic clips that should hold it on the air vent grid, broke after inserting the item about 8 times. (yes, I did it gently because I didn't want to break it.Mounting Bracket: The second choice (after the clips broke) was to use the mounting oval to hard mount the device. This was mounted in a F150 but never taken off road and after 3 months, the unit would no longer interface with the cradle because the mounts plug had worn down so much it would not stay in contact.I would not buy this again because the weight of the radio is way too heavy for any of the brackets of mounting devices.
