Alex,

Thank you for the fine feedback in both of your messages.

The antenna is in a flat mountain valley far from any trees, but it has a 
long low house running from about 7 meters to about 27 meters from the base 
of the vertical tower.  Other buildings and wiring are rare and farther 
away.  The site is very "open" other than the one close house.  There are no 
other towers or antennas on the site.

I understand that the effect of the environment is impossible to calculate, 
but is there a general direction that the environment moves the 
resistance... does it normally move the resistance up from the calculated 
values or its it sometimes up and sometimes down... What is the experience 
that most LF operators have found?

I am only curious about this....   My intention is to measure the installed 
antenna with its upper loading coils in place, and then add the amount of 
fixed and variable base loading necessary to make the antenna resonant.  I 
understand that this is the normal method... Is this correct?

J.
