I recently ordered their Tower Book, since the ham stores were out of stock at all locations when I checked, and picked it up from Amazon at a very reduced price with free shipping.

>> Hi
>> I want to thank everyone on this alias to suggest running HFTA.  I spent and couple of hours tonight and now realized  that this was a very valuable exercise. Since I promised to report back some findings here it is:
>> 
>> I got a couple of directions with slopes. My slope to Europe especially is a very even 300 feet drop off over the first 2500 feet.  This seems to be working extremely well. To Europe as an example, I can get up to a 11 dbi gain at 4 degrees elevation angle on 40 with 2 el. Yagi at 55 feet.  On flat ground that same antenna at that height would perform 15 dbi lower (-4).  
>> If I switch to a 3 el yagi at 55 feet on 20 m, I seem to even max out at 16 dbi at 3 degrees elevation. Almost too good to be true.   
>> 
>> 
>> Summary:
>> Unless I am doing something wrong with HFTA, in my case there is no need at all to go above 55 feet (size of a small tubular crank up mast).  Remember my goals from below, no huge expenditure and good DX setup 40 and up.

>> 
>> I have received an overwhelming response to my questions.  I should have mentioned a few more points/requirements:
>> 
>> - single multiband beam 40 - 10. No stacks. I am running verticals and wires hanging in trees and can hear ok, but are not being heard well on 40 for example.   I want at least a few S units improvement and F/B would be great as well.
>> - I like DX and DX contesting, but casually.    Focus on Europe.
>> - self supporting, no guy wires
>> - low profile to appease to wife and neighbors
>> - cheap. This is a hobby for me and I am not retired (:-)
>> - account for the sloping terrain, so if it can be lower because of it, yes, yes, hence cheaper.
>> 
>> I understand that any multi-band beam is a compromise.
>> I understand that any beam might not work to its maximum into all DX directions (different angles needed).
>> 
>> At this point, I want to thank all of you for your input. I will run the suggested software and report back with my findings.

>> Thanks
