7. DATA SHEET 58538A and 58539A Lightning Arrestors for GPS Systems Key Features 58538A • Small, waterproof unit for installation in a
grounding panel where the antenna cable enters the building • Protects receiving equipment only (must be used in conjunction
with the 58539A) 58539A • Larger package for installation in a grounding panel where the antenna cable enters the building, or
close to the GPS antenna • Protects antenna system components and receiving equipment Key Benefits 58538A •
Reduces the energy of a nearby lightning strike when used in the communications band up to 2.5GHz • Flexible
configuration to suit your system requirements 58539A • Reduces the energy of a nearby lightning strike when used in the GPS L1 frequency
range • Flexible configuration to suit your system requirements Lightning can damage GPS system components and receiving
equipment, even without a direct hit. This can result in costly repairs and critical interruption of service. The 58538A Lightning Arrestor and
58539A GPS L1 Lightning Arrestor are designed to work in conjunction with a lowresistance, low-inductance ground to protect your GPS
receiver and elements of the antenna system from lightning discharges and fieldinduced electrical surges. Symmetricom 58538A The 58538A
is a small, waterproof unit designed to operate in the communications band up to 2.5 GHz, and to take much of the energy out of a nearby
lightning strike. This unit is typically installed in a grounding panel where the antenna cable enters the building. The 58538A will protect
receiving equipment only, and must be used in conjunction with the 58539A. Symmetricom 58539A The 58539A is a larger package optimized
for use in the GPS L1 frequency range. It will reduce the energy from a nearby lightning strike to a level where it will not harm either antenna
system components or receiving equipment. The 58539A may be used alone or with the 58538A, as described in the following paragraphs.
Protect Antenna and Nearby Components Only When placed close to the GPS antenna, the 58539A will protect the antenna from surge
voltages and currents that can be induced in the antenna cable by lightning. Antenna system components, such as line amplifiers, will also be
protected if located between the antenna and the arrestor. Protection of receiving equipment is discussed in the following paragraph.
Protect Receiving Equipment with a Recommended or Economical Configuration In systems with short in-building cable lengths (<4 m), a
single 58539A installed where the antenna cable enters the building is sufficient to protect downstream equipment. Systems with long in-
building cables need one 58539A at the entrance to the building and one near the receiver. This diverts to ground any voltages induced in the
in-building cable by the electromagnetic fields generated by the lightning strike. For a more cost-effective solution, the 58538A can replace
the 58539A at the building entrance, as long as an 58539A is placed near the equipment. Protect Both Antenna and Equipment Your GPS
system can be configured to protect the antenna and nearby components as well as receiving equipment. Such systems require one 58539A
installed properly near the antenna. A second 58539A (or 58538A, as needed) is required at the cable entrance into the building to protect
downstream equipment. Finally, a third 58539A should be placed near receiving equipment if the in-building cable run is greater than 4
meters. Page 1 of 2 _x000C_DATA SHEET 58538A - 58539A Low Maintenance Cost due to Replaceable Surge Arrestor Capsule Both the
58538A and the 58539A have integrated gas-filled surge arrestor capsules. During lightning strikes, the capsules can direct a single 40 kA
current impulse or multiple 20 kA impulses to ground without being destroyed. Periodic replacement of the capsules ensures that the
arrestors are performing at their best. There are many other products with gascapsule technology which do not have replaceable capsules.
This makes periodic maintenance expensive because the whole arrestor must be exchanged. Replacement capsules are offered as 0960-1297.
Durable and Easy to Install The 58538A and 58539A are designed for easy installation in either indoor or outdoor locations. Both arrestors are
waterproof and corrosion resistant, and both feature sturdy Type-N connectors. The 58538A can be mounted directly into a grounding panel.
The 58539A has builtin mounting holes for mounting to a flat surface. 58539-60602 is provides a low-resistance, low-inductance, 300-mm
grounding cable to the 58539A. Longer cables may not provide proper grounding due to increased resistance and inductance. . . . 58538A
