低功率電波輻射性電機管理辦法
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
This radio transmitter(IC: 3568A-USB-N53) has been approved by Industry Canada to operate with the antenna types listed below with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device.
| Ant. | Antenna Type | Connector | Gain (dBi) | Remark |
| A | Dipole Antenna | Reversed-SMA | 5.00 | TX / RX |
| B | Dipole Antenna | Reversed-SMA | 3.00 | TX / RX |
| C | Dipole Antenna | Reversed-SMA | 3.00 | TX / RX |
| D | Dipole Antenna | Reversed-SMA | 2.00 | TX / RX |
| E | Dipole Antenna | Reversed-SMA | 2.00 | TX / RX |
This Class [B] digital apparatus complies with Canadian ICES-003.
For product available in the USA/Canada market, only channel 1~11 can be operated. Selection of other channels is not possible.
