I'm hoping I'm not imposing too much but can some of you's 'alls do a 
quick modeling for me?  I don't have the necessary software and/or 
expertise and I think this will be a piece of cake for you experienced 
folks.

Present configuration:    KT36XA up 72 ft. on self supporting tower. 
 All by itself.  5 elements on 20M on 32 ft. boom.

Future proposal:    KLM 6 element 20M monobander on 58 ft. boom up 120 
ft. along with a KLM 3 element 40M beam with 32 ft. boom.  Tower will be 
Rohn 45 guyed with Phillystran.

Questions:   

What will the 6 el beam up 120 ft. do that the 5 el at 72 ft not do?
Will the two antennas interact with each other in a bad way?
Which should be on top and by how much?

The 40M beam was orginally planned but I've come upon a really really 
good deal on a new in the box 6 el 20M beam.
Tnx in advance and please don't take much of your time.  Phil  KB9CRY
