 ``` I've been waiting for the opportunity to share this technique with the world. It looks like the time has arrived! But first a brief aside... I've been amazed by the claims that extraterrestrials layed the foundations of the Egyptian pyramids with their sides EXACTLY along East/West and North/South lines. You've seen the books and TV reports, stating the accuracy down to the limits of our modern-day instrumentation! Well here's how you can duplicate this feat... Start with a level surface. This can simply be a small piece of paper, a 4x8 sheet of plywood, your driveway, or the desert sands. Second, place an item above your level surface that will cast a shadow. A pencil, a fencepost, or a tree will do. Third, mark the end-point where the shadow meets your surface. (A sunny day is best here... plenty of them out in the desert!) Fourth, wait an hour, two, three, or so. Fifth, mark the end-point of the shadow when you return. (Hint: it will have moved toward the east.) Finally, draw a string between the original shadow mark and the final shadow mark. You now have a precise line which runs east and west. Line the elements of your yagi to this line and the boom of your antenna will point north and south. It's amazing how those extraterrestrials figured this out and taught it to the Egyptians! :-) 73 de Bob - K0RC Technique author unknown -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html Submissions: towertalk@contesting.com Administrative requests: towertalk-REQUEST@contesting.com Problems: K7LXC@contesting.com Sponsored by Akorn Access, Inc & KM9P ```
