Topband: Verticals on the beach

[Stan Stockton]

Thanks, Dan!

I have absolutely no concern about what I am achieving from about 240 degrees CW to about 25 degrees.  I don’t think it gets much better for a single element.  In terms of wavelength my 160m vertical is as close as your 20m vertical example at about 8 feet.

It’s simpler to explain this way.  Draw a line across a sheet of paper and everything above that line is salt water, everything below the line is average ground and the line is running from the left at 215 to the right at 35 degrees.  Then you have a 160m vertical that is 70 feet below the line and you want to see the far field pattern at 45 degrees.  You don’t want it to assume the salt water doesn’t exist because you have chosen an azimuth that doesn’t get you to salt water for 15 miles.  The antenna is omnidirectional and little doubt the salt water provides some enhancement to points that are 45 degrees and thousands of miles away.  Specifically what I want to find out is how much louder I would likely be in Europe from 25 degrees to 50 degrees if the vertical was on that line you drew as compared to being 70 feet below the line.

 Can AutoEZ be used to model this?

Regarding the wonderful AutoEZ program..lf anyone is using EZNEC and isn’t also using AutoEZ, it would be roughly equivalent having a cell phone for the sole purpose of looking up turn by turn directions and choosing to opt out of the feature that would allow you to push a button and say “Take me to McDonalds”
