Rich,  

I have never measured the ground conductivity here but I'm pretty sure it is prety good.    We are close to wetlands adjacent to Carquinez Straight.  And not too far from the Napa River.

On DX the vertical won hands down on every sig.  On closer in, stateside stuff stuff the horizontal dipole was the best.  Not suprising, the vertical dipole has a lower angle of radiation.  I also checked to be sure the tower wasn't interacting with the vertical dipole to be sure it didn't screw up th pattern.  I am very pleased with the vertical dipole's performance (for DX)
