The through-the-lid antenna from Aclara reaches 100 percent of meters in pits and vaults while providing high read rates. Designed for installing communications modules in meter pits and vaults, the unit enables utilities to reuse existing metal lids or replace them with lids that radio frequency signals can penetrate. The antenna installs through an industry-standard-sized hole drilled in the pit-lid and attaches to the Aclara STAR network meter transmission unit and meter. 800/297-2728; www.aclaratech.com.
