[TowerTalk] Beverages and verticals

[cqtestk4xs at aol.com]

Things are progressing on getting the station up and running and in less than two weeks I should have the tower up.  I have room for  Beverages up to around 800 feet.  One will be running from NW to SE and the other NE to SW.  I hope to make them bi-directional.  I plan to make use of them on 160 and 80, but may use them some on 40.  The antennas on 80 and 160 will be vertically polarized so the Beverage is important there.  However, on 40 the antenna is a Yagi so the Beverages will not be as important.

A couple of questions:

1.  I can make them any height, but am considering 10 feet  with a rise to maybe 14 over the driveway.  Thoughts on the height, and the "hump' over the driveway?  

2.  The NE/SW run will be running pretty evenly downhill and will drop from around 1150 feet to around 1000 feet above sea level.  While this is great for a Yagi, how will it affect the Beverage going downhill?  Conversely, how will the rise of 150 feet affect the Beverage in the opposite direction?

3.  Finally, a 4 square will be used for transmit on 80, with the same drop.  Should I expect any enhancement  in the direction of the drop and conversely, any degradation in the uphill direction?  I think I know the answer to both questions, but want some opinions.  I can't model this on N6BV's HFTA so right now it's guesswork.
