Annex B: Method to evaluate compliance with the limits of human exposure to radio frequency electromagnetic energy for AM broadcasting undertakings

This annex provides a two-step methodology to evaluate Safety Code 6 (SC6) compliance distances for AM broadcasting undertakings.

Since compliance distance will likely be in the near-field region of AM transmitting antennas, both the electric field (E-field) and the magnetic field (H-field) need to be considered. The evaluation of compliance distance is performed in two steps, as follows.

Step 1: Determining the applicable field-strength limits

The first step consists of determining nerve stimulation-based (NS) and specific absorption rate-based (SAR) reference levels for both the electric field and the magnetic field for the AM site of interest. These limits are provided in the SC6 document, Limits of Human Exposure to Radiofrequency Electromagnetic Energy in the Frequency Range from 3 kHz to 300 GHz. When evaluating the 50% UE (uncontrolled environment) limits of SC6, the SC6 NS-based limits shall be multiplied by a factor of 0.5, while the SC6 SAR-based limits shall be multiplied by a factor of 0.71.

The most stringent field strength limit (the lower field strength limit) between the NS limit and the SAR limit shall be used.

Step 2: Calculating the theoretical compliance distances

Tables B1-B9 provide the electric and magnetic field-strength levels at various distances from the base of AM broadcasting towers for a number of frequency and tower electrical lengths. Since the tables are normalized to a radiated power of 1 kW for an AM single tower, the field-strength limits evaluated in Step 1 need to be adjusted for the actual nominal station power. In the case of tower arrays, the radiated power of each tower can be used to adjust the field limits if they are known. Otherwise, a conservative prediction is to be made by assuming all transmitted power is radiated from each antenna. In such a case, the appropriate value from the tables could be used to define the zone of minimum compliance distance around the array, consisting of circles with appropriate radii, each of which are centred around a tower in the array.

In the case of a shared AM transmission tower broadcasting on multiple frequencies, a minimum compliance distance should be calculated for each frequency using the method described in this annex, and assuming that the radiated power is the sum of the powers of all stations transmitted by the tower. The largest calculated minimum compliance distance should be selected as the overall minimum compliance distance for the tower.

The following formulas shall be used to adjust field strength levels based on applicable limits determined in Step 1:

\[ E_{ajusted} = \frac {E_{lim\left(50 \%\right)\_step 1}} {\sqrt {P_{nominal} \times 1.78}} \]


(eq. B.1)
\[ H_{ajusted} = \frac {H_{lim\left(50 \%\right)\_step 1}} {\sqrt {P_{nominal} \times 1.78}} \]


(eq. B.2)
where:
Elim(50 %)_step1
is 50% of SC6 limits (E-field) determined in Step 1 (V/m rms)
 
Hlim(50 %)_step1
is 50% of the SC6 limits (H-field) determined in Step 1 (A/m rms)
 
Pnominal
is the unmodulated radiated power from the tower (carrier only) in kW if known; otherwise, the station’s nominal (authorized) radiated power in kW shall be used

Once the adjusted field limits are calculated, tables B1-B9 provide the theoretical compliance distances for various frequencies and electrical antenna heights in degrees (360° = 1 wavelength). For electric or magnetic field values that fall in between the data points in the tables provided, the first data point with an electric or magnetic field value below the target value for compliance should be selected.

Note: Electrical antenna height (in degrees) is calculated using the following formula:

Electrical_Antenna_Height(°) = Antenna_Height(m) × 1.2 × frequency(MHz)
(eq. B.3)

Tables B1-B9 can be used directly to evaluate the electric and magnetic fields for facilities that use both:

  • electrical height within 1% wavelength (i.e. within 3.6 electrical degrees) of the electrical height for the given table
  • carrier frequency at the frequency or the adjacent channel frequency for the given table

For antennas that do not correspond to the above conditions, the electric and magnetic fields will be evaluated as follows:

  • For electric field, the available tables using the next higher and lower frequency, and next higher and lower electrical length, shall be consulted (four readings). The largest distance reading shall be retained as the compliant distance for electric field.
  • Separately for the magnetic field, the available tables using the next higher and lower frequency, and next higher and lower electrical length, shall be consulted (four readings). The largest distance reading shall be retained as the compliant distance for magnetic field.

The SC6 compliance distance shall be determined as the largest distance among the two distances retained for the electric and magnetic fields. The compliance distance as determined using this method is referenced to the surface of the tower and cannot be less than 2 m.

Annex C: Demonstration of compliance with radio exposure for low-power and very low-power undertakings

To demonstrate compliance with Safety Code 6, low-power and very low-power broadcasting stations must provide the following information:

  • General information on the site, such as its location and type of antenna structure.
  • A summary of the parameters of the station being considered, all broadcasting stations within 1 km and any other transmitting stations within 100 m (frequency, maximum ERP).
  • An explanation of all access controls that prevent the general public from accessing the area. A picture, sketch or diagram of the site/tower showing fencing or locked doors would be beneficial as part of the explanation. If the installation involves a free-standing tower with no fencing, indicate the anti-climbing measures installed on the tower.
  • A demonstration of compliance using either the distances in the tables below or detailed calculations using the formula described in section 8.1.
  • A sentence attesting that the site is compliant with the Safety Code 6 limits.

Tables C1, C2 and C3 are based on the following assumptions:

  • The overall contribution from other radio apparatus in the vicinity is considered non-significant.
  • “Distance from antenna” is the distance from the centre of radiation of the antenna to any point 2 m above from the ground or any points accessible to the public.
Table C1: Compliance distance for the AM Broadcasting Service
AM Broadcasting Service Distance from antenna (m) Transmitter power limits (W)
Low-power (electrical height below 60 degrees) 14.5 Less than 100
Low-power (electrical height 60 degrees or above) 4 Less than 100
Table C2: Compliance distance for the FM Broadcasting Service
FM Broadcasting Service Distance from antenna (m) ERP limits (W)
Low-power single polarization 5.1 50
Very low-power single polarization 2.3 10
Low-power dual polarization 7.2 50
Very low-power dual polarization 3.2 10
Table C3: Compliance distance for the Television Broadcasting Service
Television Broadcasting Service Distance from antenna (m) ERP limits (W)
Low-power - Channel 2 to 6 (analog) 7.2 100
Low-power - Channel 7-13 (analog) 14.4 400
Low-power - Channel 14-51 (analog) 43.6 5000
Very low-power - Channel 2 to 6 (analog) 4.1 32
Very low-power - Channel 7-13 (analog) 4.1 32
Very low-power - Channel 14-51 (analog) 7.8 160
Low-power - Channel 2 to 6 (digital) 13.8 370
Low-power - Channel 7 to 13 (digital) 17.6 600
Low-power - Channel 14 to 51 (digital) 31.5 2600

Note: The distances above can also be used if more than one low-power station is on the same tower and all of the following criteria are met:

  • There is more than one station/frequency being used at the site, and they are all of the same type of broadcasting service (e.g. all FM).
  • The total power of those individual stations added together does not exceed the maximum power level allowed for one station of the same type.
Annex D: Letter of intent

This is to inform you that [company name] has applied to Innovation, Science and Economic Development Canada (ISED) and the Canadian Radio‑television and Telecommunications Commission (CRTC) for the authority to [operate a new / modify an existing] [AM / FM / TV / DTV / S‑DARS] station to serve [community name].

Annex E: Antenna pattern file format

The “.pat” antenna files are ASCII files that can be created or edited with any text editor or word processor. The files store a combination of angular positions and pattern attenuation values. Antenna attenuation can be given either as dB values or as relative fields. Both azimuth and elevation pattern values can be stored. In order to do a proper normalization of the antenna patterns for calculation, the angles of maximum radiation must be included. Interpolation is performed for azimuth or elevation angles that are in between angular positions given in the file.

The file format is as follows:

 'Antenna Name', GAIN, PATVAL
AZA(1), AZPAT(1)
AZA(2), AZPAT(2)
.
.
AZA(N), AZPAT(N)
999
NUM_ELPAT, NELVAL
ELPAT_AZ(1)
ELA(1,1), ELPAT(1,1)
ELA(1,2), ELPAT(1,2)
.

ELA(1, NELVAL), ELPAT(1,NELVAL)
ELPAT_AZ (2)
ELA(2,1), ELPAT(2,1)
ELA(2,2), ELPAT(2,2)
.
.
ELA(2,NELVAL), ELPAT(2,NELVAL)
.
.
ELPAT_AZ (NUM_ELPAT)
ELA(NUM_ELPAT,1), ELPAT(NUM_ELPAT,1)
ELA(NUM_ELPAT,2), ELPAT(NUM_ELPAT,2)
.
.
ELA(NUM_ELPAT,NELVAL), ELPAT (NUM_ELPAT,NELVAL)

'Antenna Name': The name of the antenna, limited to a maximum of 20 characters and enclosed in single quotation marks. The name is used to uniquely identify the antenna.

GAIN: The maximum gain of the antenna in dBi. Optional value, which is not used in calculations.

PATVAL: This number indicates whether the tabulated pattern data is given as relative values or in dB. PATVAL = 1 for relative field; PATVAL = 2 for dB (with negative sign).

AZA (1..N): Azimuth angles for azimuth pattern values. These need to be in ascending order in the file. Maximum azimuth increment is 45 degrees.

AZPAT (1..N): Azimuth pattern value in relative field as a decimal fraction, or in dB, depending on the value of PATVAL.

N: Total number of azimuths listed in the file, limited to a maximum of 721 points.

999: A special code that separates the azimuth plane from the elevation plane antenna data.

NUM_ELPAT: Number of elevation pattern descriptions, limited to a maximum of 72 “sections.”

NELVAL: Number of elevation pattern values that are specified for each elevation section, limited to a maximum number of 181 points per section. Each elevation section must use the same set of angles.

ELPAT_AZ: The azimuth in degrees for which the following elevation pattern is given. The value must be between 0 and 360 degrees, inclusive.

ELA: Elevation angle of which the elevation pattern is specified. The angles must begin above the horizon (positive sign) and progress to below the horizon (negative sign).

ELPAT: Elevation pattern value in relative field as a decimal fraction, or in dB, depending on the value of PATVAL.


A sample “.pat” file is listed below. The pattern values are listed in dB (PATVAL = 2), there are 26 azimuth values given and 2 elevation sections, each having 19 elevation values. The first elevation section is for 0 degree azimuth, the second cut for 180 degree azimuth.
