The Aries A-SWR 460 Digital Power/SWR MeterThe same meter was available under the Workman brand a year or two ago. It didn't catch on because of poor marketing. I wasn't aware of this meter until just before it was discontinued. The catalog had very little information and the picture wasn't even eye catching. One day thumbing through a distributor's catalog for meters, I stopped and was intrigued by the possibility of a digital SWR meter. Then realized it was a power meter too. I tried a couple and was sold on them. When it was time to reorder they were gone.Now a reasonable facsimile is available under the Aries brand. The only apparent difference is the brightness of the LED display. The Workman is brighter but the A-SWR460 is readable in well lit areas. In the dark it's easy to read. It could be possible to modify the unit to increase the brightness of the display, I'll look into it and find out what can be done.The following is the instruction sheet supplied with the meter:A-SWR460 DIGITAL-SWR/POWER METER
This unit is a compact device for checking operation of the CB transceiver. It may be installed and left permanently connected.For SWR and POWER measurements, the unit uses a bridge to get the actual forward and reflected values from the antenna system then the SWR and POWER is calculated by the microprocessor. The operator can accurately and quickly match the antenna to the transmitter, at the same time the power being fed into the antenna can be determined.Operation:1.Turn the transmitter off and disconnect the antenna coaxial cable of the transmitter output.2.Install the unit, "RTX" connector to the transmitter output, and "ANT" to the antenna connector. A short cable equipped with male connector on both ends will be required between the transmitter and the unit (NC-535). Connect the supply cord of the unit to the power supply, and switch "ON" the unit.3.Turn the transmitter "ON" and the unit automatically displays the SWR and POWER being fed to the antenna. Right side portion of the display indicates the SWR. and the left side portion of the display indicates the POWER.4.A 1:1 ratio is the ideal match adjustments on the antenna system should he made so that the SWR is as low as possible. A SWR of 2 is considered satisfactory, taking into account the line losses and slight mismatching.*Please note that this instrument will handle up to 500 W. Power over this rating may cause damage to the unit. Sample Displays
