Uh, that's easy. Your vertical is low noise because it is so lossy. The 
two 2 foot radials are probably not doing much of anything, and you're 
working against lossy ground.

Put 25-30 1/4 wave radials 1 foot off the ground and you'll soon find the 
antenna is much more noisy, but it will be a lot more efficient, too.
