Please find in the attached the updated manual page of the product. 2. In our product manual, we recommend antennas to be used with our equipment by their size and gain. At 2.4GHz band, we recommend 2’ panel antennas and 2’-8’ parabolic antennas. The gains of these antennas range from 20dBi to 33.5dBi. As examples, we recommend to our users some typical antenna vendors now in the market, such Gabriel, Radio Wave, Andrew, CSA Wireless, etc. Though of different make, antennas of the same dimensions have very similar gains and other specifications, as indicated in the following table. Antenna Type and SizeGain (dBi) 2’ parabolic20.7 4’ parabolic27 6’ parabolic31 8’ parabolic33.5 Please find in the following table detailed information of some antennas as examples. Since there are numerous antenna manufacturers and product models in the market, this is only a partial list. However, I hope the examples shown on the following table can demonstrate the consistency of antenna specifications regardless of the make and model of the antennas.

Yours truly Caroline Yu International Product Manager Western Multiplex Corporation INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS FEBRUARY 2000 PAGE 3-20SECTION 3: INSTALLATION & ADJUSTMENTS 3.10Antenna Installation & Alignment The antenna installation consists of mounting the antenna on the tower, building roof, or other location that provides line-of-sight path clearance to the far-end location. In general, antennas smaller than 2 feet diameter are not recommended for urban areas due to their wider beamwidths, which results in higher interference susceptibility. For 2.4 GHz Tsunami radios, a minimum of 4 foot (1.2m) diameter antennas, or larger, are recommended. Antennas should be ordered with a suitable mounting kit specific to the site requirements. For example, specifying round or angle tower leg adapters, or a roof tripod as necessary. The antenna must be very rigidly mounted, with adequate room for azimuth and elevation adjustment. The antenna polarization must be the same at both ends of the link, either vertical or horizontal. In general, antenna mountings require a support pipe to which upper and lower support brackets are attached with “U” bolts. The antenna and optional elevation and azimuth adjustment rods are then mounted onto the support brackets. The whole structure must be adequately grounded for lightning protection. The antenna system must always be installed according to the manufacturer’s instructions. Unless special test equipment is available, two operating Tsunami terminals are required to align the antennas. Alternatively, a CW generator may be used to transmit a signal toward the end under alignment. The antenna is coarse aligned using visual sighting and then fine aligned using the receive signal level (RSL) voltage of the Tsunami. The RSL voltage reading can still be used to peak antennas even if the radios have not synchronized, however far-end RSL cannot be measured from the near-end terminal until radios are synchronized. To coarse align the antenna, first set it for flat elevation (no up or down tilt) using a spirit level. Then point it at a heading marker obtained using a compass back-bearing from an adjacent location, (ideally, 100 feet or more away from the antenna). INSTALLER CAUTION: Antennas used for this device must be fix-mounted on permanent outdoor structures to provide 5 meters or more separation from all persons during device operation to comply with FCC RF Exposure requirements. Installers should contact the manufacturer for applicable antenna gain and type restrictions to ensure compliance.

Federal Communications Commission Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 Attention: Reviewing Engineer The HZB-S24-12 (MODEL 31190) radio is a full duty-cycle product exclusively designed for fixed-mount point-to-point applications (Please refer to Page 1-1 of the Installation and Maintenance Manual ). Each radio’s inputs are connected to external equipment through the radio’s interfaces. The RF output port is connected to a RF cable or a waveguide, which connects on the other side to an antenna usually installed on top of a building or a tower. It is impossible to use the radio in any mobile application. The HZB-S24-12 (MODEL 31190) radios need to be professionally installed outdoor either on top of a tower or a tall building. The installation sites are inaccessible to the general public. Only installation engineers may get close to the radio antenna during system installation. For the safety concern of the professional installers, we put a warning message on Page 3-20 of the product manual recommending installers stay at least 5 meters away from the antenna during system operation. The maximum output power allowed for the 2.4GHz spread spectrum radios is 1W, and the biggest antenna to be used with our 2.4GHz radios is of 8’ diameter (33.5dB gain). The worst case EIRP is when the highest gain antenna is used: Maximum EIRP = 30 + 33.5 – (33.5-6)/3 = 54.3dBm (269W); The power density at 5 meters from an antenna is: S = EIRP/4 π R 2 = 0.9 W/m 2 = 0.09 mW/cm 2 < 1 mW/cm 2 Where: S = Power density R = distance to the center of radiation of the antenna In the cases of using 4’, 6’ and 8’ parabolic antennas, the near field power density is S nf = 16 η P/ π D 2 . The worst case of near-field power density is when the radio output at 1W, η =1, and the antenna diameter D=4ft. S nf ma x = 16 x1/ π (4x0.3048) 2 = = 3.4 W/m 2 = 0.34 mW/cm 2 <1 mW/cm 2 Where: S nf = maximum near –field power density P = power fed to the antenna η = aperture efficiency D = antenna diameter So in all the above-mentioned situations, the power density is compliant with the limit for General Population/ Uncontrolled Exposure as specified in rule 1.1310.
