eLMS: antenna

Used to store directional antenna patterns.  Records are keyed off the application ID and should be sequenced in the order of azimuth.  Records will have at least 36 tabulations including any additional azimuths specified by the applicants.  Nondirectional antennas will not be acknowledged in this table.

column

type

description

lms_application_id

varchar(32)

Primary index used for all applications.  Corresponds with the FCC’s application identifier used in LMS and therefore can be used to cross reference with FCC raw data.   Unless otherwise indicated, all relational tables in eLMS are linked by lms_application_id

azimuth

int

Azimuth in degrees (0~359)

field

double(5,3)

Field value of antenna in the direction of [azimuth].  This is used to determine effective radiated power in a particular direction.  To determine ERP in a particular direction, multiply the ERP of the station by the square root of [field].

additional_azimuth

int

Indicates [1] if the [azimuth] is not of the standard 10 degree increment.
