 Drag coefficients for lattice tower

    depends on Reynolds Number

for super-critical flow - Cd for cross section ~ 0.5 times that for equivalent sharp-edged tower with same solidity

Cross section with circular members

Antennas and open-frame structures

some members may be in super-critical flow - others in sub-critical flow
