I was fortunate to have know W3BES.. W3GM.. He developed a method to tilt over
his ( Six) Rohn 25 towers at his Contest station in PA. The method is the
falling derrick design. theses towers were all 100ft except the low ten and
fifteen meters. were 80 ft. The design was simple .. 4 way guying and a 50% gin
pole ( derrick ) This design has been copied with great success by a number of
fellow armatures over the years. I my self have two 100' rohn lay over tower
up for over 20 years. 40mtr tower @100 50' gin pole derrick Hy Gain Discovery
3 element shorty 40 19 years . .replaced last fall with a XM240, 15 mtr tower
three 5/5/5 five element yagi HY-Gain).
Other local who copied W3GM's design had all sorts of antenna configuration
from three stack Christmas tree 20/15/10, tri bander shorty 40 to full size
three element 40 mtr antennas.
Are these designs in the Rohn Bible No.. will a city give you a building
permit No.. YMMV
But I have raised and lowered mine up and down many many times over the years
. The gratification or removing your Hy-gain 3 element 40mtr antenna install a
new rotor feed lines and XM240 by your self in two days works for me ..
