The collectors and nodes in the EnergyAxis System operate under Part 15.247 of the FCC Rules. Suitable antennas
are omni-directional antennas of unity gain or 3 dB gain (2.15 and 5.15 dBi, respectively). Elster recommends the
following, which are rated to withstand 100 mph winds and are fitted with Type N female connectors:
■ PCTEL/MAXRAD MFB9300 Series (Tessco P/N 61900) for unity gain (2.15 dBi)
■ PCTEL/MAXRAD MFB9153 Series (Tessco P/N 74330) for 3 dB gain (5.15 dBi)
Regardless of the antenna selected, the antenna should be mounted with at least two MMK1 pipe clamps (Tessco
SKU 68869). The antenna should be mounted in the clear, as free from the conductive or metallic obstructions as
possible. The connectors should be sealed for waterproofing.
