Interpretation of EIA-222-F

Interpretation of EIA-222-F

Interpretation of EIA-222-F


I'm wondering if anybody can help define for me the meaning of "z", the "height above average ground level" as used in the -222-F spec.

I understood it to mean the same as the FCC's Height Above Average Terrain but have been told by a tower engineering company that it simply means the height above the base of the tower.

Does anybody have any thoughts on this?

RE: Interpretation of EIA-222-F

I think "Z" in page 4 sec. (2.2 of EIA/TIA 222f) shoul be select from average of tower area from minimum two time of height ( 2*tower height ).
for example in towers who erected in top of the building z = (height of building + Zi). [Zi=height above tower base].
