<div dir="ltr"><div><div><div><div><div><div>George,<br><br></div>Simplest answer, whatever works.<br><br></div>That being said, Dave, N1SAG, and I did extensive testing on 432 with his pair of yagis mounted side by side (like mine) horizontally. He was in a bit of a pit, and the thought was if he had elevation adjustment he might be able to manipulate the manner by which his signal propagated over his "horizon". In short, he never was able to achieve the desired or expected results. His observation was that there was virtually no difference within the range that "worked"...meaning if he had the elevation anywhere between just below level up to some angle (don't remember specifically what that was, he would have a signal and adjustment would not vary the level within that range. Outside that range he had nothing. This is one guy, in one set of circumstances, but we were both quite frankly surprised. <br>
</div>Further, WA2WEJ had his single yagi on an elevation rotor for vertical to horizontal excursions, and often adjusted somewhere between to see if there was ever a circumstance where it would be helpful. The only time it was useful was when the need arose to work to differently polarized signals at once without major degradation. He found that 45 degrees didn't seriously attenuate either signal, Your mileage may vary. You may even find an eggbeater may be just the ticket for this one elusive signal, as Tom has found with the Larry contact. Berlin Larry has used a stacked "double diamond" antenna to propagate over a major obstruction and has had decent results. Then there is the phenomenon noted while parked at work, all Waterbury stations pointed at me, and moving 8 inches forward or backward brings up one and drops out another.<br>
</div>In short, EXPERIMENT, EXPERIMENT, EXPERIMENT!!!<br><br></div>Good luck and let me know how it works out!<br><br></div>Bob<br></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Sun, Feb 2, 2014 at 9:38 AM, George Andrews <span dir="ltr"><<a href="mailto:gandrews@ntplx.net" target="_blank">gandrews@ntplx.net</a>></span> wrote:<br>
