As my top band antenna is right on the shore of the Baltic Sea I find this
discussion extremely interesting. The Baltic Sea's Salinity is low, in my
area in the range of 5-6 psu compared to the ocean average of 35. I wonder
if and how I can make use of the sea to improve top band antennas.
I am now using two elevated radials for my top loaded vertical, could I
improve its performance by running a few radials into the sea?
How would I translate psu into values that NEC understands?
