Sec. 15.111  Antenna power conduction limits for receivers.
    (a) In addition to the radiated emission limits, receivers that 
operate (tune) in the frequency range 30 to 960 MHz and CB receivers 
that provide terminals for the connection of an external receiving 
antenna may be tested to demonstrate compliance with the provisions of 
Sec. 15.109 with the antenna terminals shielded and terminated with a
[[Page 771]]
resistive termination equal to the impedance specified for the antenna, 
provided these receivers also comply with the following: With the 
receiver antenna terminal connected to a resistive termination equal to 
the impedance specified or employed for the antenna, the power at the 
antenna terminal at any frequency within the range of measurements 
specified in Sec. 15.33 shall not exceed 2.0 nanowatts.
    (b) CB receivers and receivers that operate (tune) in the frequency
