8.71:1 indicates the maximum VSWR the amplifier can see with a 1db attenuator on the output. Here is more info on itMake a 1dB attenuator to put on the output - you lose 20% of your output at the gain of not blowing the devices
This immediately means the VSWR can not go over 8.7:1 with a dead short or open on the output (the two worst possible cases)
