A High-Gain Receiver enables the reception of radio signals outside of their usual range. The Signal rating of a device indicates the range at which normal receivers can detect, receive, and make use of their transmissions. But the radio waves don't stop sharply at that distance; they are merely attenuated. A high-gain receiver detects the attenuated waves, amplifies them, and does its best to sort out any noise or static that gets mixed in. A high-gain receiver can pick up a transmission at one Signal rating beyond the transmitting device's usual range. For example, it could pick up a transmission from a Signal 1 RFID tag at up to 100 meters, and it could pick up a transmission from a Signal 5 Fairlight Caliban at up to 10 kilometers.
If there is no other significant radio-frequency electomagnetic activity in the area, then even an untrained person of average intelligence can operate the HGR with a fair chance of success, requiring only a single hit on Electronics Warfare + Logic. If the desired transmission might get lost among, or drowned out by, other transmissions, then the threshold increases accordingly:
- Deserted area, eg middle of the ocean, other signals include long-range radio and sunspots: 1
- Rural area, other signals include entertainment broadcasts, weather channel, etc.: 2
- Low-density settled area, within the Signal range of hundreds of other active devices including commlinks, GridGuide, AROs, etc.: 3
- High-density settled area, within the Signal range of thousands of other active devices: 4
- Hub airport, electronics trade show, Grand Central Station: 5
Why add this to your campaign's gear shopping list?
a) They already exist IRL, so why not?
b) One more complication for gamers who like a complex, nothing-is-absolutedly-safe setting. Your PAN might be sniffed by a person across the room or across the street with a HGR, unless you're in a shadowrun cafe/bar or secured building with its own Faraday cage or wifi-blocking paint.
I'm guesstimating $150 and Capacity 2. Alternately, *any* radio signal scanner can be used as an HGR, as long as the user makes an appropriate EW + Rating test.
