The work you and N1SAG did is applicable to what I would try to do. The antenna will always be horizontal. I may do a pilot with a three element as that will be a lot easier and provide proof of principle. I think that I want to get the two meter beam up and the station running sometime in the spring. I have a carpenter friend who will help with the installation. Not sure how high up it will be. Probably thirty feet above ground level. The wind, ice and subzero temperatures really stress things. My installation of the Cobra Ultralight would have been up for two or three years in CT. It came down during an icy stretch of windy subzero temperatures. Our low so far was -18 F, not corrected for wind chill. We get stretches of 1 to 4 below zero, uncorrected for wind chill. The temperatures don’t bother me, I just stay in if it is close to 20 below. It puts antenna installation in another category altogether. I already bought some grease for mechanical things that is good to -40. I will have to make sure all the rotators have low temperature grease. <u></u><u></u></span></p>

I would like to have the 2M beam up, the HF dipole and HF vertical up by summer. I plan to put a 40 M loop up that should also do well on 10 M. I just have to make sure nothing is located where a moose might get tangled up. We have an assortment of critters that run through the yard. Got a moose on game camera about ten feet from our front door. We saw a mama bear and cub within thirty feet of the house. I think I scared them away. There is also a bobcat that has been running around in the yard, perhaps after squirrels and birds. <u></u><u></u></span></p>

Simplest answer, whatever works.<u></u><u></u></p></div><p class="MsoNormal" style="margin-left:.5in">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. <u></u><u></u></p>
</div><p class="MsoNormal" style="margin-left:.5in">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.<u></u><u></u></p>
