At my previous QTH in Schaumburg, Illinois I had a tower
up to about 75 feet with a Hygain TH6DXX on top for 20,
15 and 10 meters. For 40 meters I had a center fed half
wave dipole in an almost vertical position strung from the
top of the tower sloping down to the ground. It slopped
at something of an angle so it was not perfectly vertical.
For 80 I had a top fed quarter wave element in a sloper
configuration angled, as best I recall, to about a 45 degree
angle.
I had that system up for probably not more than a year
and a half because in the later part of 1979, we moved to
Texas. Yes, I lowered the antennas, disassembled the sections
of Rohn 45G tower and they along with the disassembled TH6DXX
were loaded on the moving van along with all of our goods.
In Schaumburg I had sufficient real estate to string guy
wires for the tower, but in Bedford, Texas I did not. The
layout of my lot did not lend itself to guying which would
be needed if I intended to raise the tower to its former
height. I decided that I probably would not raise the tower
to the same height I had previously done.
I installed enough tower sections to get the tower to 25
feet. I did not put on the top section. My plan was to eventually
raise the tower to perhaps 50 feet and put the beam on top.
I had no idea how I was going to handle antennas for 80
and 40 though. One thing at a time.
In the meantime I installed a half wave center fed dipole
for 40 which had the apex up a little over 25 feet using
the top of the tower as a mount. The antenna slopped in
somewhat an Inverted V configuration. I am not sure why
I selected that band but I suppose I considered it a good
compromise for one band if that was all I was going to have
for a while.

A brief side bar with a description of the operation in
Schaumburg, IL. Obviously with the antenna system I had
installed there, HF performance was ideal. Due to the nature
of my job (lots of business travel) I was not able to operate
as much as I would have liked to. Nevertheless, during that
time I set out to and accomplished the Bicentennial WAS
Award offered by the ARRL during the Bicentennial
year 1976. That was no mean feat considering that I only
became licensed that year and collecting confirmed QSL's
for all of the contacts with all 50 states is not always
an easy task.
After accomplishing that task I became motivated to try
for a 5BWAS (Five Band Worked All States). I hit it hard
and heavy. I came close to accomplishing it too. I worked
and confirmed contacts with all fifty states on all HF bands
but two. Yes, that included AK and HI on 40 and 80 meters.
I lacked (as I recall) something like two states on one
band and one state on the other band. I believe those were
15 and 20 meters. I don't recall which of the two I lacked
confirmed contacts on. The states I needed were the more
close in states to Illinois and those aren't always easy
to get if propagation tends to "skip" over them
because of the close proximity. Anyhow, that's where I was
when I found myself having to pull everything down in preparation
for the move to Texas.
