Dear John: As others have said - expect a lot of coupling. However, even a
second read did not disclose what you wish to place on a 40 foot tower - or
if you expect to use the new tower as the end for one or more wires.

Clearly the example of a 3 element 40 meter beam at 40 feet makes no sense.

Thanks for your advice! The more views I get, the less likely it is
for me to make bad decisions.

Here is where my thinking is now:

I need to put the second tower wherever it will be most useful to my
purposes. The existing vertical array and its radials are expendable.
It can be reconstructed if desired at another time. I believe it has
served my purpose and it is time to move on. Installing a tower is not
a trivial matter and the decisions should be made to take advantage of
the opportunities it provides.

My interests are a little different than most Hams. I enjoy studying
more than operating. Building and using antennas is an important part
of the hobby (addiction?) to me. When I made the retirement move to
this location I made certain that I would be able to pursue that path.
I have enough real estate, wife does not care what I choose to do with
the hobby, and the neighbors are indifferent as well! I consider all
the antennas to be temporary and everything must be accessible. Twice
this past week I have lowered the existing Tribander to 25 feet
because of weather forecasts. Change is the rule rather than the
exception!

If I encounter excessive interaction I will just consider it another
condition to explore. I started out with the idea that this would be a
30 foot VHF-UHF structure but it appears that I can reach a little
higher and stronger than that.

I will keep the options open as best I can to provide a second
structure that lends itself to further experiments.

At least that is what I am thinking today...
