I have to agree that the Wilson 1000 is a better antenna.
At Copper the K-40 is $39 and if you want to turn it into a magnet mount it will cost an extra $19.
The wilson magnet mount is $69 so they are similiar in cost.
You can also get replacement whips for the wilson's much easier.
go to http://www.iglou.com/copper and check it out for yourself. or you can go to www.k40.com and
look at there line
