How long is the PowerPole terminated DC power cable that ships with the Flex 6400 transceiver?

    Since there was no response on this forum, Matt at FlexRadio sales was more than helpful to answer this prospective buyer question. The power cable length furnished with a new radio is six (6) feet. I'm laying out my new station and needed to know if it would be necessary to break out the hydraulic crimper and **** splices to make a longer power cable or not. Product as well as user forum support is important for one to get up and stay running with a particular brand of radio. Elmers on this SDR technology are definite stress relievers for us old analog dinosaurs :0).
  • Is it possible to get an 8' cable ??
  • Also ( forgot) what gauge is the cable wire ???

    Hi Michael, I think Flex only sells the 6 ft cables. You can go to the Powerwerx web site and order a custom cable for a reasonable price if you don't want to make your own. A 10 footer made of # 10 wire with 1/4 inch ring terminals at one end and 45 amp Anderson Power Pole connectors at the other is around $26 USD.

    Just a caution. There may be noticeable power loss through a cable of this length, though some of it may be due to the use of power poles. I reconfigured my station to put the power supply next to the radio with a 1 foot power cable with ring connectors at the ps and power poles at the radio. When I adjust the ps to get 13.8 v at the radio during transmit, the ps is set to almost 15 volts, so about 1 volt drop.

    10 ft of #10 wire at 14 VDC and 25 amps will have a voltage drop of approximately .5 V. #8 wire will reduce that to about .3 V.

    For reference, 6 ft of #10 under the same conditions will have a drop of .3 V.
