From the popularity of the DBJ-1 came the DBJ-2.  Based on the DBJ-1, the DBJ-2 was designed for easy deployment in the field to primarily aid in extended handie talkie coverage.  It is available in HAM (144-148 MHz and 440-450 MHz) or Commercial (152-157 MHz and (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, Wouxun, Baofeng, etc).  This includes BNC, SMA (male), and SMA (female).
