Ant#--identifies the particular antenna at a site. Usually would be #1 but could be several numbered sequentially.
Freq ID--identifies the particular frequency on the license. Usually would be #1 but could be several if there is more than one frequency on the license. They would be numbered sequentially.
Paging Rec--identifies the number of paging receivers on that frequency (if any).
The repeater frequency is identified as FB2. A base station is FB. Control stations are FX1. Mobiles and portables are identified as MO. There are several additional Station identifier classes. See the FCC web site for more information. Tones are assigned locally and are not on the FCC license. Also only TRANSMIT frequencies are listed on the license. Fixed stations require a location. Mobiles and portables have an "area of operation."

Just my observations

Freq ID = useless, means nothing for scanners
Antenna # - if there is more than one antenna on the site for that one license
Paging Rec = if the Freq is Primarily used for Paging this is the number of Receivers

Yup, Rptrs are FB2, FB4, FB6, FB8
FCC Station Class Codes - The RadioReference Wiki

I was inable to find anything else about this topic and if its in the wrong place please let me know.

I have been playing on the ULS system and just have trouble reading and understanding all the deginations.

For instance:

What all these mean.

Ant#

Freq
ID

Paging
Rec.

Also is there a way to tell Repeater frequencies?

And tones other than scanning and pulling it that way?

Yep, frequency ID doesn't even appear on some licenses. It's inconsequential.

Theoretically, there should be no Antenna #0. That is basically the antenna that's used at each location. Different figures may be entered for gain, directional characteristics (which don't appear in ULS or on the license, but are used for coordination), etc, but most preparers are sloppy and leave them each at 1. In theory, a Loc. 1, Ant. 1 arrangement with multiple frequencies would mean one multi-frequency base station, but in real life it's not usually the case.

MO = mobile, MOI = Itinerant mobile (no permanent location). This is a nationwide license and none of these frequencies are protected for primary status.

SC = special conditions. Click on the field and it will go into greater detail, for example, "Operating Nationwide including Hawaii, Alaska, and US Territories." or "Frequency Special Conditions
Operation on this frequency is on a non-interference basis to Canadian operations and you must accept all interference from operations in Canada. Licensee is responsible for resolving any complaints of interference to Canadian systems arising from operations on this frequency, including, if necessary, cessation of such operations."

Paging receivers are usually there if a site has no associated mobiles, but alerts receivers. Some agencies use the field to indicate the number of volunteer pagers, but most preparers leave it blank, whether they're there or not.

None of these appears to be licensed as a repeater - BUT - there was a period of time where low power repeaters were allowed to be listed as "MO" stations. So it might be possible. Being "nationwide" they can be anywhere, but they have to be on a non-interfering basis to site-based licensees.

You will not find tones on an FCC license. The FCC doesn't license CTCSS or CDCSS tone or code operation. That's between licensees to hammer out.
