I bought a RTL-SDR Blog R820T2 RTL2832U 1PPM TCXO SMA Software Defined Radio (Dongle Only) on Amazon and a package of three antennas. $40 for everything. Using SDR# and the whip, I can tune FM broadcast and my local VHF repeater, nut what are the two little dudes good for? There is no frequency marking on them--only the brand name.They are cylinders of about 0.5 inch diameter and maybe 2.5 inches long. The dongle is rated up to 1.7m gigahertz and I saw somewhere that these are "helical" antennas. Thanks. |

They are designed for transmitting on higher UHF frequencies. For *receiving*, the larger whip should hear on those frequencies just as well as the smaller ones, if not better. Mark AI4BJ |

Thank you. I have been toying with the idea of getting an xcvr sdr dongle such as a "hackRF one". The dongle puts out in milliwatts. Is there any kind of amplifier that would drive these antenna? |
