PTP SOLUTIONS GUIDE

Although Motorola’s PTP 300, 400, 500 and 600 Series radios are designed to withstand extreme

conditions, they are often mounted on high towers, frequently with external antennas, making the radios

prime targets for lightning strikes. The Motorola Fixed Point-to-Point Lightning Protection Unit (PTP-LPU)

is designed to protect a Motorola PTP 300, 400, 500 or 600 Series radio from the harmful effects of power

surges induced in the cables by nearby lightning strikes. By grounding the power surges before they can

harm the units, the Motorola PTP-LPU gives PTP radios the best protection from the harmful effects of

lightning, although 100% protection is neither implied nor possible.

PTP Lightning Protection Unit (PTP-LPU)

Product Description

The PTP-LPU is a high-speed, high-current, solid-state device that is encased in a rugged metal case

designed to hold up against ice, snow and rain and withstand winds up to 150 mph (242 kph). The projected

operational life of a PTP-LPU is 10 years, even when continually exposed to the elements. Because of its

small form factor and minimum number of components, the cost-effective unit is easy to transport and

install. As a replacement for the Transtector surge arrestor (ALPU-ORT), the PTP-LPU is priced for a fast

return on investment.

Because the units can be installed with new deployments or easily added to existing PTP radios, current

and prospective operators of a Motorola PTP network can reap the beneﬁts of the PTP-LPU’s lightning

protection capabilities.

For more details, refer to the PTP-LPU’s speciﬁcations at the end of this document.
