Review on Enhanced Mini-Whip Mf/Hf/VHF Shortwave Active Antenna with SMA Output Interface: Amplify Signal Reception and Improve Range by Jody Kashani

The product was delivered without instructions. The only indication of voltage was in the description, otherwise you wouldn't know what voltage it needs. Offset T has RF on one side and RF+DC on the other. Without instructions it is not known what goes to the radio and what goes to the antenna. I assumed the RF+DC would go to the antenna to power the circuitry on this board. HF side to the radio. In any case, I caught more than one FM station. You will also need to provide your own cables as they are not included.
