The now defunct Wilson WT61 foot tower comes with a brochure saying it
can be strengthened to 20sqft wind load in a 50 mph wind by guying.
They show a single bearing being placed on the 3rd, top section with 4
guy cables. In discussions with hams who had guide crank up towers
collapse, there seems to be a difference of opinion over whether crank
up towers can or should be guyed. The argument is that when the wind
blows, the guys transfer the pressure down the tower. If the crank up
cable is supporting the tower, this can place stress on the tower and
down she comes! The Wilson has a single pin on a spring (mine gone)
where a small role may be pulled to place a non-slip pin into the top
of the first of three sections. A friend said this might take stress
off the cable that cranks and holds the tower, permitting guying. I
am interested in experience and opinions?
