The DX2700 Active 1 antenna has been replaced by the HW-DT8 Antenna,
The DX2700 was a boosted antenna with high gain boost (600 timessignal strength or 28 DB) and needed power to the head.
The replacement antenna DT8 does not need boosting to work the same as the DX2700 which is amazing (see Utube video when on home page simply CLICK on DT8 antenna bar Read info & scroll down to video.
