- EPA is the actual area seen by the wind of an appurtenance (antenna, mount, etc.) multiplied by a force coefficient. It is not necessarily the value published by the appurtenance manufacturer.
- ANSI/TIA/EIA-222-F-1996 recommends that designs be evaluated by a registered professional
- Custom engineering of the 1200 TLWD guyed tower is available for non-stock loading requirements
- All tower kits include complete tower steel and hardware, complete guying system, anchor shafts and one (1) foundation design based on normal soil.
- Ship weights do not include dunnage or guy spools
- Ship length of guy cables is 10% greater than the lengths shown
- All EPAs are given in square feet
- Roof-mounted towers require an engineering review
- For towers where the consideration of ½-in radial ice is either specified or prudent for the locale, the selected tower must meet all Effective Projected Area (EPA) requirements for both the ice and no ice conditions.
- Designs assume towers are ground-mounted on a flat, level site with a dead weight of 250-lbs (no ice) and 400-lbs (with ½-in radial ice) applied at the top of the tower
- Wind speeds shown with ½-in radial ice are not concurrent wind speeds. All towers designed with ½-in radial ice consider the standard EIA reduction in wind load with ice.
