The primary protectors offer the surge currents a direct path to earth ground versus the undesirable “sneak” paths it may find through the equip Properly installed and grounded primary protectors will dramatically increase the surge withstanding capabilities of the PureWave equipment. Surges that exceed the maximum ratings of the primary protector devices will eventually cause them to fail,short or open, as the application warrants, such that further surges will not damage the end equipment. While a failed primary protector still results in a service outage, it does prevent further damagemore expensive end equipment. A Base Station that is installed outdoor on the tower or mast (ODU) is especially vulnerable to lightning surges. Good surge mitigation practice starts with the lightning rod and its connection to a proper sized down conductor. The ground down conductor should be as straight as possible and avoid incidental contact with other conductors such that it represents the path of least resistance to earth ground from the lightning rod. The tower/mast is also earth grounded tosafety, and generally presents a less desirable path to ground to surge currents. ODU equipment and external primary protection devices are mounted to the tower/mast and should be bonded tat the same point on the down conductor. This practice is intended to avoid ground loop currents that may flow from differences in potential between the tower/mast structure and down conductor while large surge currents are flowing in them respectively. Good surge mitigation practice also makes use of shielded cables with peripheral shield grounding to minimize potentials induced on circuit conductors. These cables should also be secured to the tower/mast at regular intervals to create from conductors which are carrying surge currents. This practice avoids incidental contact or possible insulation breakdown from high surge potentials. A Base Station that is installed indoor units (IDU) requires similar protection as (ODU). Primary protection devices are installed on all cables just prior to entry of the facility and bonded to an earth ground stake. Likewise, the cable shields are grounded at the entry panel which should be bonded to the same earth ground stake. IDU equipment may also be vulnerable to surges entering via the AC power connection and steps should be taken to install a proper AC Surge Suppressor device to complete a well protected installation. 3.1 Lightning Protection Installation The following are considered to be the main elements that constitute the components of a lightning protection scheme.  Lightning Rod  Base Station and Antenna Grounding  Down Conductor  Coaxial and/or Cat 5 Cable Shield Grounding Quantum 1000 Base Station User Guide Rev 1.1, Page Grounding and Lightning Requirements Proper lightning protection requires the use of external primary protectors to complement the secondary protection built into the PureWave equipment.

Quantum 1000 Base Station User Referring to figure 41 above, the “Height Above Antenna” above the highest item of equipment (generally the antenna) must be at least twice the distance (2 x d) between the outer surfatower. This will ensure a “protection cone” of 60 degrees around the tower (30 degrees each side from the lightning rod). In areas of high lightning activity, the “Height Above Antenna” should be increased to up 5 times the distance. 3.3 Down Conductor The purpose of the Down conductor is to provide the shortest and most direct path to the earth. grounding of the down conductor to earth must be of ground resistance no more than 5 ohms. 3.4 Co-axial and/or Cat 5 Cable Shield Grounding The purpose of the Shield grounding is to minimize the potentials induced on circuit conductors plus keep the cable shields at earth potential (0V) for personnel safety. All ground lugs must be properly bonded to the grounding system of the protected compall Antenna cables. Prior to entry into any facility, the cables must be properly grounded to the building primary ground system at the building entrance panel. In case of an indoor installed Base Station then this will apply to the coStation to the Antenna. This is because these cothe indoor and the outdoor. In the case of an outdoor installed Base Station, then this will apply to the Cat 5 cabconnection to the Base Station. In the case of an installation of the Base Station, it is the Cat 5 cable and the power that provide the inter-connections between the indoor and the outdoor. 3.5 Grounding and Bonding The National Electric Code requires that any accessible metallic surface of electronic equipment be connected to earth ground for personnel safety. Earth ground connections are achieved by direct connections to the AC power ground at the IDU and by a grounding lug on the ODU. A Craftattach a proper size wire to the ODU ground lug during installation, else the ODU chassis will float at whatever potential appears at the shield connection of the coax. 3.6 Recommended Connection of a Bonded Ground We will now examine the concept of a bonded ground. Bonded connections for reliable, gas tight joints between conductors require removal of all paint from both contact surfaces and holding them together under high pressure such as with a bolt or screw. The use of toothed washers is alcause the conductive surfaces to bite into each other for improved connectivity and eliminate movement of the conductors due to vibration.

All ground lugs must be properly bonded to the grounding system of the protected compall Antenna cables. Prior to entry into any facility, the cables must be properly grounded to the building primary ground system at the building entrance panel. In case of an indoor installed Base Station then this will apply to the co-axial cables that connect the Base Station to the Antenna. This is because these co-axial cables provide the only inter-connection between In the case of an outdoor installed Base Station, then this will apply to the Cat 5 cable and power connection to the Base Station. In the case of an installation of the Base Station, it is the Cat 5 cable and connections between the indoor and the outdoor. Grounding and Bonding equires that any accessible metallic surface of electronic equipment be connected to earth ground for personnel safety. Earth ground connections are achieved by direct connections to the AC power ground at the IDU and by a grounding lug on the ODU.
