Transmitters in this frequency range should be fitted with a single isolator providing a minimum of 20 dB isolation. 9.10 Transmitters in the 72 to 76 MHz range shall have a band pass filter providing a minimum of 30 dB of attenuation 1.0 MHz removed from the operating frequency. Transmitters in this frequency range shall also be fitted with dual isolators providing a minimum of 50 dB isolation. 9.11 Transmitters in the 88 to 108 MHz range shall have a band pass filter providing a minimum of 30 dB of attenuation 1.0 MHz removed from the operating frequency. Transmitters in this frequency range shall also be fitted with dual isolators providing a minimum of 50 dB isolation. No transmitters with a transmitter power output of over 100 watts shall be permitted within SNO911 facilities. In addition, some facilities may not allow use of transmitting equipment in this frequency range. 9.12 Transmitters in the 108 to 225 MHz range shall have a band pass filter providing a minimum of 15 dB of attenuation 1.0 MHz removed from the operating frequency. Transmitters in this frequency range shall also be fitted with dual isolators providing a minimum of 50 dB isolation. 9.13 Transmitters in the 225 to 400 MHz range shall have a band pass filter providing a minimum of 20 dB of attenuation 1.0 MHz removed from the operating frequency. Transmitters in this frequency range shall also be fitted with dual isolators providing a minimum of 50 dB isolation. 9.14 Transmitters in the 400 to 512 MHz range shall have a band pass filter providing a minimum of 20 dB of attenuation 2.0 MHz removed from the operating frequency. Transmitters in this frequency range shall also be fitted with dual isolators providing a minimum of 50 dB isolation. Window filtering with broader responses may be authorized on a case by case basis. 9.15 Transmitters in the 512 to 746 MHz range shall have a band pass filter providing a minimum of 20 dB of attenuation 2.0 MHz removed from the operating frequency. Transmitters in this frequency range shall also be fitted with dual isolators providing a minimum of 50 dB isolation.
