Hi and thanks for taking the time to read this. =20
The winter storms we have been getting here over the past few years =
seem to be getting stronger and stronger. I put a 60' freestanding =
tower up over recent years, and on it I have a 4 element 5 band quad. =
Last year I put 3 guys on the tower at around 45'. They were not =
extremely strong wires, but I put them on to give that little extra =
support. =20
During the winter we had 2 very severe wind storms the worst had =
winds of 95mph+. The tower was fine but the quad had minor damage =
around $20.=20
It is the tower I want to protect in the high winds, as the quad =
can be repaired easily without much expense.
This summer I am going to replace my temporary wires with a more =
substantial arrangement. I intend to put just one set of wires on at =
around 48' up the tower. I do not want to go higher as it would begin =
to get close to the quad. (Bottom of the elements are around the 54')
Questions
1. Do I put a set of 3 guy wires or 4 guy wires equally spaced around =
the tower.
2. What direction should they face taking into account the worst =
storms come from the SW, W, NW.
3. How far should the guys be anchored from the base of the tower, I =
appreciate the ARRL suggests at least 60% of the tower height, but if =
needed they could go up to 60ft from the base. =20
4 The tower weighs around 750kg (1650 lbs), any idea what size of =
load may be on the guy wires, in such high winds. (I appreciate this =
would be hard to calculate as surface area would need to be known, a =
ball park figure would be great however ). If it is of any help the =
tower is 24"X18" and made from 2" angle iron)
A lot of questions but any answers to any of them would be very much =
appreciated. If you wish you can reply to me directly at =
glenn@gi0kvq.freeserve.co.uk
Again many thanks for your time.
