Fellow radiators:

To Find Your Soil's Electric Conductivity

1) Go to: http://websoilsurvey.nrcs.usda.gov/app

2) Click on the big green button, "Start WSS".

3) Follow step 1 of "Three Basic Steps" on the first page.

Typing your address under "Quick Navigation" is the

easiest method. Remember to spell out street, circle...

When using the + and - zoom feature, click on + or -.

Then place the cursor at the point you wish to be the

center of your next map and click.

4) Click on "view".

5) Click AOI tab which is just above the map and outline

(draw a box

around) your Fresnel Zone.

6) Follow the second step "View/Explore" by clicking

the "Soil Map" tab.

7) Click the "Soil Data Explorer" tab.

8) Click the "Soil Properties and Qualities" box which is

just above the map.

9) Click the "Soil Chemical Properties" box.

10) Click the "Electrical Conductivity" box.

11) Toward the bottom of the page, locate "Top Depth" and

enter 1.

For the bottom depth enter 144 for 14 Mhz, 360 for 1.8 Mhz.

12) Click inches.

13) Click "View Rating".

14) In the table, read in the column "Rating (millimhos

per centimeter)".

15) Use the millimhos/centimeter number as mS/m.

Thus, 17 millimhos becomes 17 mS/m. This is the

electrical conductivity of your Fresnel Zone.
