set up the equipment as shown in Figure 5.4. Reset the Receivers angle to 0-degrees(the horns should be oriented as shown with the longer side horizontal). 5 Record the meter reading when the Polarizer is aligned at 22.5, 45, 67.5 and 50-degrees with respect to the horizontal.6 Remove the Polarizer slits. Rotate the Receiver so the axis of its horn is at right angles to that of the Transmitten. Record the meter reading, Then replace the Polarizer slits and record the meter readings with the Polarizer slits horizontal, vertical, and at 45 degrees.
