My experience with various Littlite mounting systems is they all suck, that is if you're planning to yank the gooseneck around a lot (trust me you will!)
Other than the panel mount (BNC plug) the weighted base is your best bet. However, there's a DIY alternative which I hit upon and it works the better than all the other attachment methods. You just need to plan where you're going to want it:
Take the chassis apart (that's the little box at the other end of the goosenck with the rheostat) by removing the two screws on the top (either side of the rheostat knob) That will release the subchassis on the bottom. (This has nothing on it, it's just a piece of metal.) Screw the subchassis down to your shelf (it's predrilled) and then slide the main chassis with goodseneck over it, secure the two top screws and you're done. Really solid, and it doesn't matter where you position the gooseneck.
The reason I mention this, is because although you can get the 18" gooseneck with the weighted base, it can tip over if you're not watching the position of the gooseneck relative to the base. Plus the base may limit placement.
