36v, 4.44A (160W) Power Supply is required for all 4/5 element antenna’s. This ships with all new DB42, DB36, DB18/18E, DB11, 3E, and 4E antenna’s and is available as a replacement/upgrade part. For cable runs over 400 feet we recommend the Remote Driver Board (see controller information page). The remote driver board allows you to run cat5e cable up to 2000 feet away from the tower base (power required at tower for this option).
If you are having problems with your 40m looped element we highly recommend upgrading to this higher current output power supply, to the new sweep design which has a smoother transition between the fiberglass pole and PE sweep, and also upgrading to our new EHU contact brush which helps reduce friction in the EHU.
