260, yes!
I have a Shakespeare 5200 whip, sadly there is no great mounting location with an Arch. Even is I lay it back, all the angles are just a little wrong for a simple "lay down"
I am still looking for a radio, and may go with a New Uniden (or something close). The GPS antenna would be a nice touch. Unless I get a Great deal on an older radio.
I believe the last one was mounted below the stereo just inside the door to the Cuddy, and I have debated on putting it below or moving it to the console.
10-4 on the other info! (great stuff)
