  * This table should be empirically determinated by measuring the signal
  * strength generated by a RF generator directly connected into
  * a device.
+ * This table was determinated by measuring the signal strength generated
+ * by a DTA-2111 RF generator directly connected into a dib7000p device
+ * (a Hauppauge Nova-TD stick), using a good quality 3 meters length
+ * RC6 cable and good RC6 connectors, connected directly to antenna 1.
+ * As the minimum output power of DTA-2111 is -31dBm, a 16 dBm attenuator
+ * were used, for the lower power values.
+ * The real value can actually be on other devices, or even at the
+ * second antena input, depending on several factors, like if LNA
+ * is enabled or not, if diversity is enabled, type of connectors, etc.
+ * Yet, it is better to use this measure in dB than a random non-linear
+ * percentage value, especially for antenna adjustments.
+ * On my tests, the precision of the measure using this table is about
+ * 0.5 dB, with sounds reasonable enough to adjust antennas.
