I think somone , smarter than me , will have a answer,,,, "you are
driving down the hiway and see a cell/antenna tower, it is off the

tall the tower is,,,????? Is there a simple (kiss) way to find out?
thanks in advance. cl.

If in the U.S.A., contact the FCC and get the information from their
database. Elsewise, contact the wireless regulatory agency of the
country that the tower is located in.

In the USA if it has a light on it then it is over 200 FT tall. If there
is no light on the tower it is less than 200ft tall. 200 ft is the magic
number for the FAA and the FCC for tower lighting.
If you can see the section joins then count them an mult by 20 ft. 20 ft
is the height of the average tower section. Your tower could use 30 or
40 ft sections though. You will have to inspect the tower up close to
estimate the height of a section.

Almost right, over 200 feet or close to an airport or heliport, in
which case the max unlighted height slopes to zero at the airport
and follows a slope that depends on the type of airport.

Title 47, Part 17.21 and Part 17.17

Correct.... But most cell towers are not near airports.

And, most cell towers are not in the U.S.A.
