Clearance Check FAQs

1. What is the purpose of the new automated antenna structure clearance check?

2. All towers that do not meet the glide slope and are over 60.96 meters (200 feet) require an FCC Form 854. Is there a software program or person whom I can contact to verify tower registrations and/or whether these towers require FAA filing for glide slope?

3. Is there a software program or person whom coordinators can contact to verify tower registrations and/or whether they require FAA filing for glide slope?

What is the purpose of the new automated antenna structure clearance check?

The Wireless Telecommunications Bureau (WTB) is responsible for ensuring that antenna structures do not become a hazard to air navigation. It carries out this responsibility by

1. checking whether FAA notification and FCC registration is required for each antenna structure prior to authorizing wireless operation from the site and
2. making sure each license application is consistent with the location and height as registered.

Therefore, if the FCC requires registration, WTB will not allow an application to be filed without a valid registration number, unless, of course, it is accompanied by a request for a waiver.

You have several tools at your disposal to consider whether an application will be "cleared" with respect to antenna registration.

1. You may determine if registration is necessary by using TOWAIR from the Antenna System Registration's (ASR's) Internet website at http://www.fcc.gov/wtb/antenna.
2. You may download the WTB's licensing databases to verify existing tower specifications.
3. You may use ULS to review tower specifications in your current licenses at http://www.fcc.gov/wtb/uls.

Is there a software program or person whom coordinators can contact to verify tower registrations and/or whether they require FAA filing for glide slope?

Both applicants and coordinators have several tools to use to discern whether an application will be "cleared" with respect to antenna registration. Either applicants or coordinators may

• determine if registration is necessary by using the TOWAIR software;
• download and use the FCC's free Antenna Registration software;
• download the FCC's licensing databases to verify existing tower specifications; or
• use ULS to review tower specifications in their current licenses.
