Forward gain went from 11.86 dBi (avg) at 18 degrees to 12.45 dBi (salt). Takeoff angle, interestingly, went up one degree for the better ground plane. Moving the antenna down 6 feet over salt water moved the takeoff angle up 1 more degree, from 19 to 20 degrees. 73, Pete _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "Wireless Weather Stations", and lot's more.
