How to fill out Form 7460-1, box by box
1. Sponsor and 2. Sponsor's Representative (if other than #1)
In Items 1 and 2, include the name, address and phone number of a personal contact point as well as the company name.
3. Notice of
New Construction would be a structure that has not yet been built.
Alteration is a change to an existing structure such as the addition of a side mounted antenna, a change to the marking and lighting, a change to power and/or frequency, or a change to the height. The nature of the alteration shall be included in Item 21, Complete Description of Proposal.
Existing would be a correction to the latitude and/or longitude, a correction to the height, or if filing on an existing structure which has never been studied by the FAA. The reason for the notice shall be included in Item 21, Complete Description of Proposal.
4. Duration
If Permanent, so indicate. If Temporary, such as a crane or drilling derrick, enter the estimated length of time the temporary structure will be up.
5. Work Schedule
Enter the date that construction is expected to start and the date that construction should be completed.
6. Type
Please indicate the type of structure. Do not leave blank.
7. Marking/Painting and/or Lighting Preferred
In the event that obstruction marking and lighting is required, indicate the type desired. If no preference, check “other” and indicate “no preference”. Do not leave blank.
High Intensity lighting shall be used only for structures over 500' AGL. In the absence of high intensity lighting for structures over 500' AGL, marking is also required.
8. FCC Antenna Structure Registration Number (if applicable)
If this is an existing tower that has been registered with the FCC, enter the FCC Antenna Structure Registration Number (if applicable) here.
9. Latitude, 10. Longitude and 11. Datum
Latitude and longitude must be geographic coordinates, accurate to within the nearest second or to the nearest hundredth of a second if known. Latitude and longitude derived solely from a hand-held GPS instrument is NOT acceptable.
This data, when plotted, should match the site depiction submitted under Item 20.
NAD 83 is preferred; however, latitude and longitude may be submitted in NAD 27. Also, in some geographic areas where NAD 27 and NAD 83 are not available other datum may be used.
It is important to know which datum is used. Do not leave blank.
12. Nearest: City: State
Enter the name of the nearest city and state to the site. If the structure is or will be in a city, enter the name of that city and state.
13. Nearest Public-use (not private-use) or Military Airport or Heliport, 14. Distance and 15. Direction
Enter the full name of the nearest public-use (not private-use) airport or heliport or military airport or heliport to the site.
Enter the distance from the airport or heliport listed in #13 to the structure.
Enter the direction from the airport or heliport listed in #13 to the structure.
16. Site Elevation (AMSL), 17. Total Structure Height (AGL) and 18. Overall Height
Item 16: Enter the site elevation above mean sea level and expressed in whole feet rounded to the nearest foot (e.g. 17'3” rounds to 17', 17'6” rounds to 18'). This data should match the ground contour elevations for site depiction submitted under Item 20.
Item 17: Enter the total structure height above ground level in whole feet rounded to the next highest foot (e.g. 17'3” rounds to 18'). The total structure height shall include anything mounted on top of the structure, such as antennas, obstruction lights, lightning rods, etc. Item 18: Enter the overall height above mean sea level and expressed in whole feet. This will be the total of Item 16 + Item 17.
19. Previous FAA Aeronautical Study Number (if applicable)
If an FAA aeronautical study was previously conducted, enter the previous study number.
20. Description of Location
Description of Location: Enter the relationship of the structure to roads, airports, prominent terrain, existing structures, etc. Attach an 8-1/2” x 11” non-reduced copy of the appropriate 7.5 minute U.S. Geological Survey (USGS) Quadrangle Map MARKED WITH A PRECISE INDICATION OF THE SITE LOCATION. If available, attach a copy of a documented site survey with the surveyor's certification stating the amount of vertical and horizontal accuracy in feet.
21. Complete Description of Proposal
Complete Description of Proposal, ITEM #21. For transmitting stations, include maximum effective radiated power (ERP) and all frequencies. For antennas, include the type of antenna and center of radiation (Attach the antenna pattern, if available). For microwave, include azimuth relative to true north. For overhead wires or transmission lines, include size and configuration of wires and their supporting structures (Attach depiction). For each pole/support in Item 21, include coordinates, site elevation, and structure height above ground level or water. For buildings, include site orientation, coordinates of each corner, dimensions, and construction materials.
For alterations, explain the alteration thoroughly. For existing structures, thoroughly explain the reason for notifying the FAA (e.g. corrections, no record or previous study, etc.).
Date, Typed or Printed Name and Title of Person Filing Notice, Signature
Enter the Date, the Typed or Printed Name and Title of Person Filing Notice, and the Signature. I agree to mark and/or light the structure in accordance with established marking & lighting standards as necessary.

(2) Any air navigation facility, airport visual approach or landing aid, aircraft arresting device, or meteorological device meeting FAA-approved siting criteria or an appropriate military service siting criteria on military airports, the location and height of which are fixed by its functional purpose.
