PCB Antenna specifications The internal antenna configuration for the module utilizes a PCB dipole that must be placed in a vertical orientation. This dipole has the dimensions shown below:
4.2. External Antenna Connector The external antenna configuration utilizes an on-board a U.FL connector. The outside enclosure must have an RPSMA bulkhead connector. This requirement is accomplished by using a U.FL to RPSMA bulkhead patch cable with a ferrite core (Fair-Rite Products ferrite

The supporting test data may be found in the modular test report. Since this module and its associated set of approved antennas have been certified as a Modular Radio, this allows the end user to integrate this module into an end-product without the requirement of re- certifying the radio module. The module-integrator is responsible for the unintentional conducted and radiated emissions and must verify that the integrated product is compliant with the rules associated with unintentional radiators. The module integrator is also required to maintain an engineering record of the verification testing and declare on the product through proper labeling and marking that the device is compliant with these particular rules. The installed modules FCC ID and IC numbers need to be clearly marked on the product with the following verbiage Contains FCC ID: ZH6-TWIGV, S9NSPBTLERF and "Contains IC: 9686A-
TWIGV and Contains IC: 8976C-SPBTLERF". 5.2. Module Integration Considerations External Antenna Systems The module, when configured for use with the external antenna connector, must use an RPSMA to N-Connector coax cable with a minimum length of 10 feet using CA-195 coax or equivalent. Antennas for use with the module:
1) Yagi type antennas with maximum forward gain of 12 dBi and mounted for vertical polarization. 2) Omni type with maximum gain of 8 dBi and mounted for vertical polarization. The incorporation of the largest practical free-space clearance around the antenna is important for maximizing overall performance. Further, the antenna must be placed such that at least a 8 inch separation distance is maintained from the antenna to all other radio transmitters. 5.3. Module Integration Considerations Top Assembly For the internal antenna configuration, it is recommended that all wiring be routed so that it does not approach the PCB antenna structure. For the external antenna configuration, the coax interconnect cable should be routed through a ferrite core as described above.

Testing Requirements for End-Product The end-product must be tested and follow the verification process for in accordance to the FCC and IC guidelines. The module needs to be powered and placed in the receive mode for this test. 5.5.

Agency Statements Federal Communication Commission Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:
Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. FCC CAUTION: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. The information in this document is subject to change without notice (Rev. A) Page 11 Industry Canada Statements This Device complies with Industry Canada License-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Le prsent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorise aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible d'en compromettre le fonctionnement. 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 permitted for successful communication. This device has been designed to operate with the antenna(s) listed below, and having a maximum gain of 1.0/2.0 dBi (Internal Antenna), 8 /12 dBi (Yagi), and 6 / 8 dBi (Omin). Antennas not included in this list or having a gain greater are strictly prohibited for use with this device. The required antenna impedance is 50 ohms.
