Based on the DBJ-1, the DBJ-2 was designed for easy deployment in the field to primarily aid in extended HT (handie talkie) coverage. It is available in HAM (144-148 MHz / 440-450 MHz) or Commercial (152-157 MHz / 460-470 MHz). The original article was published in March 2007 QST and is attached below. The unique feature of this kit is that it comes complete with a 6 ft extension cable and all adapters to connect to various manufacturers of handie talkies (Icom, Yeasu, Kenwood, Alinco, Anytone, Baofeng, Connect Systems, Wouxun, TYT, etc). This includes BNC, SMA-male, and SMA-female.
