The FCC does not require each antenna structure to be registered.
The "Determine if Registration is Necessary"
screen allows the user to enter and submit key information about their antenna structure in order to determine whether or not registration with the FCC is necessary. After
completing the form and clicking on the
"SUBMIT" button, the user then receives one of two reply messages:
- The antenna structure requires registration. A list of reasons is
provided; or
- The antenna structure does not require registration. A list of reasons is provided.
For more details on the FCC rules on antenna structure registration see the Code of Federal Regulations
(CFR) 47 Part 17.7 (Revision 10/01/1996), or click
here.

| NAD
83 Coordinates
|
Enter the exact
geographic location of the structure for which you
process a TOWAIR determination - entering both the latitude
and longitude in degrees (e.g., 42º), minutes
(e.g., 13'), and seconds (e.g., 10").
- Enter the
antenna structure's Latitude location
coordinates into the DD (degrees), MM (minutes),
and SS.S (seconds) data fields.
- Enter the
antenna structure's Longitude location
coordinates into the DD (degrees), MM (minutes),
and SS.S (seconds) data fields.
- Two
drop-down menus contain the four cardinal
directions and their "up",
"down", "left", and
"right" equivalents from a coordinate
(example: "N(+)" and "W(-)")
- Convert
from NAD27 allows you to convert NAD27
(North American Datum 1927) coordinates to NAD83
(North American Datum 1983) coordinates. If
you need to convert your coordinates from NAD27,
please click
here.

| Measurements
|
|
Enter the
following measurements:
- Overall
Structure Height (AGL) - The overall height
above ground (AGL) of the entire antenna structure
to the highest point, including any appurtenances.
Height is displayed in meters.
- Support
Structure Height (AGL) - The height above
ground to the highest point of the supporting
structure only (without appurtenances). Height is
displayed in meters.
- Site
Elevation (AMSL) - The elevation of the site
above mean sea level (AMSL). Height is displayed
in meters.
NOTE:
The default
measurement in the height data fields is meters.
To switch to measurement in feet, click on
"English" in the drop-down box.

| Structure
Type
|
|
Choose the
appropriate structure type from the drop-down
list that contains the different types of antenna
structures.
Available
structure types are:
- B - Building
- BANT - Building with an antenna
- BMAST - Building with Mast
- BPIPE - Building with Pipe
- BPOLE - Building with Pole
- BRIDG - Bridge
- BTWR - Building with Tower
- MAST - Mast
- NNTANN* - Antenna Tower Array
- 1st N = number of structures, 2nd N = position
of this tower
- NTOWER** - Multiple Structures
(The N is the number of structures (e.g. 2TOWER,
3TANK)
- PIPE - Any type of Pipe
- POLE - Any type of Pole
- RIG - Oil or other type of Rig
- SIGN - Sign
- SILO - Any type of Silo
- STACK - Smoke Stack
- TANK - Any type of Tank
(Water, Gas, etc.)
- TOWER - Free standing or Guyed Structure
- TREE - When used as a support for an antenna
- UPOLE - Utility Pole/Tower used to provide support for an antenna
(Electric, Telephone, etc.)
*Valid Tower
Arrays. The first NN indicates the number of
towers in an array. The second NN indicates the
position of that tower in the array (example: 3TA2
would identify the second tower in a three tower
array; 14TA12 would identify the twelfth tower in a
fourteen tower array.)
**Valid
Multiple Structure. The N indicates the number
of structures where multiple antenna structures are
present (example: 2TOWER, 3 TANK, 6BMAST, etc.)
