In addition to the definitions given in section 3 of the Consumer Product Safety Act (15 U.S.C. 2052), the following definitions apply for the purposes of this standard.
(a) Antenna system means a device for radiating and/or receiving radio waves. Where they are present, the antenna system includes active elements, ground plane elements, matching networks, element-connecting hardware, mounting hardware, feed cable, and other functional or non-functional elements.
(b) Antenna-mast system means the completed assembly of the antenna system and the mast.
(c) Base station means a transmitter and/or receiver in a fixed location.
(d) Citizens Band (CB) means the frequency band allocated for citizen's band radio service.
(e) Current means the total rate at which electrical charge is transported through the antenna-mast system in response to the applied test voltage, including both capacitive and resistive components.
(f) Electrical breakdown means a failure of the insulating material used with the antenna, such that in the Antenna-Mast System Test of § 1204.4(e) of this subpart, the current flowing through the antenna-mast system is sufficient to actuate the automatic internal cut-off of the high voltage source or exceeds the current that can be measured by the current monitoring device.
(g) Feed cable means the electrical cable that connects the antenna system to the transmitter and/or receiver.
(h) Field joint means any joint between antenna system sections or parts, or between the antenna system and the mast, that is not assembled by the antenna manufacturer.
(i) Insulating material and insulation mean a material that has a very small electric conductivity.
(j) Omnidirectional antenna means an antenna system designed or intended primarily to exhibit approximately equal signal transmission or reception capabilities in all horizontal directions simultaneously.
(k) Protection zone means that portion of an antenna system which can contact the test rod during the Insulating Material Effectiveness Test or can contact the power line during the Antenna-Mast System Test. This zone consists of those elements of the antenna system extending from the uppermost tip of an upright antenna downward to a point that is 12.0 inches (30.5 cm) above the top of the mast when the antenna system is mounted according to the manufacturer's instructions.
(l) Voltage, phase to ground, means that voltage which exists between a single phase of a three phase power system and ground.
