Four new configurations are available, including two that allow the pass-through of AISG signals. The complete product line is available today from PolyPhaser and its global network of channel partners.

The 4.3-10 connected PolyPhaser SX RF Lightning Surge Arrestor features a broad frequency range from 698 Mhz to 2.7 GHz with 4.3-10 coaxial connectors. The arrestor has a low PIM rating, which is typically PIM of -130 dBm (-173 dBc, 2 x 20 W). It is bi-directional, making installation simple and easy. Its compact size is better than other bulky quarter wave stub RF arrestors. It also has repeatable RF performance after surge events. The 10-year manufacturer’s warranty covers damage for the first 10 years of use.

The new 4.3-10 connected RF lightning surge arrestors have PolyPhaser’s patented SX filter technology that continues to outperform quarter-wave stub and gas tube technologies. The new SX protectors provide consistent performance because it takes up 40 percent less space than traditional components.
