Antennas
Each antenna is assigned to a mount and contributes wind area (EPA) and dead weight to the structural analysis.

Antenna Types
Panel Antennas
Flat rectangular antennas used for cellular service (LTE, 5G).
- EPA = Height × Width per face direction
- Most common antenna type on telecom towers
- Typical: 1.0–2.5m height, 0.3–0.5m width, 15–40kg
Dish Antennas (Microwave)
Circular parabolic dishes for point-to-point microwave links.
- EPA = projected circular area
- Wind loads vary with azimuth relative to wind direction
- Typical: 0.3–3.0m diameter, 10–150kg
Omnidirectional
Cylindrical antennas radiating in all directions.
- EPA = Diameter × Height
- Constant wind area regardless of wind direction
- Typical: 1.0–3.0m height, 0.05–0.15m diameter, 5–15kg
EPA Contribution
All antennas contribute to the Effective Projected Area of the section where they are installed. See EPA Contribution of Appurtenances for the calculation method.
caution
Missing antennas in your model means underestimated wind loads. Always model ALL installed antennas, including those from other tenants.
