## SMA, not RP-SMA
Some connectors that appear to be SMA are actually RP-SMA. If you connect an RP-SMA antenna to Jawbreaker, it will seem to connect snugly but won't function at all because neither the male nor female side has a center pin. RP-SMA connectors are most common on 2.4 GHz antennas and are popular on Wi-Fi equipment.

## Transmit Power
The maximum TX power varies by operating frequency:
* 30 MHz to 100 MHz: 5 dBm to 15 dBm, increasing as frequency decreases
* 100 MHz to 2300 MHz: 0 dBm to 10 dBm, increasing as frequency decreases
* 2300 MHz to 2700 MHz: 10 dBm to 15 dBm
* 2700 MHz to 4000 MHz: -5 dBm to 5 dBm, increasing as frequency decreases
* 4000 MHz to 6000 MHz: -15 dBm to 0 dBm, increasing as frequency decreases
Overall, the output power is enough to perform over-the-air experiments at close range or to drive an external amplifier. If you connect an external amplifier, you should also use an external bandpass filter for your operating frequency.
Before you transmit, know your laws. Jawbreaker has not been tested for compliance with regulations governing transmission of radio signals. You are responsible for using your Jawbreaker legally.
