However, if the A3 ALPHA meter is enclosed in a metal service cabinet or the antenna must be mounted higher to overcome signal obstruction, an external antenna may be used.This leaflet contains general information for installing the A3 ALPHA meter equipped with connections for an external antenna.■For information on the operation of the A3 ALPHA meter, see the A3 ALPHA Meter Technical Manual (TM42-2190B or later) or the A3 ALPHA Meter Technical Manual For Use in Canada (TM42-2195A or later)■For information on installing the A3 ALPHA meter, see the “ALPHA Meter Installation Instructions” (IL42-4001N or later)WARNING!Use authorized utility procedures to install and service metering equipment. Dangerous voltages are present. Equipment damage, personal injury, or death can result if safety precautions are not followed.Use circuit closing devices on current transformer secondaries (3S, 4S, 5S, 5A, 6S, 6A, 8S, 9S, 10S, 10A, 26S, 29S, 35S, 35A, 36S, and 36A meters). Equipment damage, personal injury, or death can result if circuit closing secondaries are not used.Connecting an External AntennaNote. This device has been designed to operate with the antennas listed below and having a maximum gain of 5.15 dBi. Antennas not included in this list or having a gain greater than 5.15 dBi are strictly prohibited for use with this device. The required antenna impedance is 50 ohms.Internal antenna: Elster Electricity P/N: 1B12150H01Local external antennas: Laird/Antenex TRA(B)9023P (3.1 dBi); Laird/Antenex TRA(B)9023NP (3.1 dBi)Remote external antennas: PCTEL/MAXRAD P/N MFB9380 (Tessco P/N 61900) for unity gain (2.15 dBi); PCTEL/MAXRAD P/N MFB 9153 (Tessco P/N 74300) for 3 dB gain (5.15 dBi)The external antenna connects to either the ILN1 option board or the ILC1 option board using a connector lead as shown in Figure 1. In addition to the standard internal antenna, there are two options available for connecting an external antenna:■Local external antenna■Remote external antenna
IL42-4020C September 20072Figure 1. Retaining clip and connector leadLocal External AntennaIf the A3 ALPHA meter is used in a metal service cabinet, using a local external antenna may be necessary. To obtain better coverage, the local external antenna can be mounted on the top of the metal service cabinet or the meter socket enclosure (see [1] in Figure 2).Elster recommends Antenex Inc.’s 902-928 MHz Permanent Mount antenna (TRAB9023P).1 To mount the antenna on the service cabinet or meter socket enclosure, drill a 5/8-inch hole into the cabinet wall with a step drill. Insert the antenna through the hole. After the antenna is mounted, the antenna’s Type N female connector can be mated with the meter’s Type N male connector.For installations where the mounting for the local antenna does not provide a conductive metallic ground plane, the Antenex TRAB9023NP (no ground plane required) may be employed. The gain and pattern are virtually identical with the TRAB9023P version and the TRAB9023NP may also be employed on metallic ground planes with good results.Remote External AntennaIf the A3 ALPHA meter is used in a metal building, or the meter is installed in a location where the site requires an antenna at a greater height to overcome blocked signals, a remote antenna may be required. If a remote external antenna is used, a lightning/surge arrestor should be installed at the bottom of the socket enclosure (see [2] in Figure 2). Elster recommends a PolyPhaser DSXL IN-LINE EMP surge filter (Tessco P/N 491574).2NOTICEDo not use a standard RG-8/U cable with solid polyethylene dielectric. The losses in solid dielectric RG-8/U cables in short distances make solid dielectric RG-8/U cables unacceptable.The most economical connection to the remote external antenna is the RG-8/U “foam” or “LMR-400” type cable. This type of cable should be suitable for distances of up to 100 feet. The foam dielectric cable will incur a loss of approximately 3.9 dB in 100 feet (or approximately 2 dB in 50 feet). The coaxial cable should be mounted at the bottom of the meter socket in “drip loop” fashion. A “drip loop” is formed by bringing the coaxial cable to a point below the meter socket and then bending it back up to the connector. This forms a U-shape, which allows water to run down the cable exterior. Antenna cables should be ordered with N-type male connectors on each end.1Antenex, 2000-205 Bloomingdale Road, Glendale Heights IL 60131. Telephone: 630-351-9007.

September 2007 IL42-4020C3The 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.Figure 2.
