My experience shows that doubling the height is equal to multiplying the 
power by 4. This is especially true if you can get above the tree-tops. 
Here in the desert, you can really increase the range by adding height. 
I bring a 25' pole to mount both the HF antenna on plus the dual band 
VHF/UHF antenna.
