Notes on US/JA 10 Meter System

November 2004

Raised bottom to 32 feet, 4 feet at a time with WB9Z, while listening to beacon stations.

That netted result that bot was now equal to top or sometimes better. (Prior, the bottom 10 at 20 feet was never better.)

Found that 120 inches of coax (about 69 degree electrical) is best, and yields stacking gain on most paths, especially to West coast.

On air reports confirm these results.
