SWL antenna distribution system
- A methodology for connecting multiple LF/MF/HF receivers to a single antenna via readily available and inexpensive 75-ohm TV cable. Custom made baluns and splitters provide impedance matching and prevent interaction between receivers.
- Small enough to carry it in your shirt pocket and powerful to fit your needs. It will be your companion for years, thanks to the "FirmwareLiveUpdate" feature. Use it for everyday packet, for APRS, as a Tracker with a GPS or as APRS digi.
