Joe, et all... I have a rather old but still useful tool for calculating depression angles to a point using lat/long and heights above mean sea level. It can be downloaded by following this link.. <http://65.173.252.46/Miktrek_Info.htm> then click on the "BDS" link. It will initiate a download. Save it where you can find it, and extract to a folder. This works very well, and is free to anyone. It was developed by a company I used to work for back when dino's roamed the earth. Broadcast Data Services is no longer around... and it was for free distribution when they were, so no issues there. One other thought, you can get lat/long from topozone.com for specific sites. I am sure you all have used topozone, so I won't go into that. Have fun...

For that matter, figure at 5 and ten miles also. At those short antenna heights you will usually want the maximum gain, unless your prime coverage is in the first half mile or so.
