Adequate signal strength must be available outside the structure as a prerequisite to achieving in-building coverage. The device is connected to an external antenna, normally located on a roof, and to one or more internal antennas placed strategically throughout the area where wireless service is desired. The VHF Signal Booster Series is a Digital Signal Booster that operates in the 136 – 174 MHz frequency range. The external antenna is typically directional, such as a Yagi or Panel antenna. Internal antennas are typically omnidirectional, although various other types may be used, depending on the coverage application. The Signal Booster amplifies both the uplink (mobile to base) and downlink (base to mobile) signals, thus facilitating communications to and from the intended wireless infrastructure. With a maximum total of 80 dB nominal gain on both the uplink and downlink, gain can be adjusted over a range from 52 dB to 80 dB in 1 dB steps.

The Signal Booster must be installed in a vertical orientation (i.e. Connectors on the bottom of the unit). • Inadequate isolation between the outside and inside antennas may cause regenerative feedback in the system. • This feedback can cause the amplifier to emit a continuous signal at maximum Amplitude, and, in some cases, interfere with normal operation of the donor site. Careful consideration of the layout and placement of the system is imperative to minimize this possibility and to minimize the amount of signal leaking from the Building. • Do not disassemble the Signal Booster. • • • • • • • • • • Danger! Refer to the 1.3 Safety Guidelines section for proper antenna selection and installation. To avoid serious injury, death and/or damage to the Signal Booster, do not install donor or server antennas near overhead power lines or high power components. Allow enough distance so that falling antennas would not come in contact with those components. Electric shock may occur if the Signal Booster is installed in close proximity to water. WARNING! Amplifier or handset damage may occur if a handset is connected directly to the Signal Booster or to the coax that leads to the Signal Booster. The Signal Booster must be connected to ground for protection. We recommend that installers do not wear jewelry or metal accessories when installing this Signal Booster. Do not place cables or tools that may damage the Signal Booster in close proximity to it. Check the installation site for hazardous conditions such as water-covered floors or badly worn or damaged cables prior to installation. Lifespan and performance of the Signal Booster may be reduced if the unit is operating outside its nominal temperature range. However, to improve reliability, it is recommended to mount the Signal Booster on a site with shelter from direct exposure to sun, rain, snow and hailing. It is not recommended to install the Signal Booster under bad weather conditions, such as: • Intense rainfall, snowfall or hail • Storm or high wind • Extremely low or high temperature • High humidity of the air WESTELL.COM ©2017 Westell Technologies 1.877.844.4274 July 2018; Doc No. VHF Signal Booster UM RA Page 24 of 95 VHF Product Manual July 2018, Rev B 5.2 Donor Antenna Installation Guidelines • Accurately determine the azimuth to the donor site. Obtain the donor site information and approval from the service provider/carrier. • Ensure that the radiation path to the donor site is unobstructed. • Mount the donor antenna at or toward the edge of the roof, in the direction of the donor site. Avoid having the RF signal from the donor pass above the location(s) of the service antennas. Normally, the service antennas are installed behind and below the donor antenna, as viewed from above. This approach helps avoid interference and feedback to and from the service antennas. • Normally, mounting the donor antenna higher will allow a less obstructed path to the donor site. However, in high traffic metro areas, avoid mounting the donor antenna higher than necessary, as the quality of the donor signal may become less stable and it is more likely to encounter adjacent channel interference. • When possible, shield the rear of a donor antenna by locating it so that any HVAC units and/or penthouse structures are behind the antenna, relative to the donor cell site location. 5.3 Indoor Antenna Installation Guidelines • Use omnidirectional antennas (see section 2.4. Optional Accessories) indoors and locate them centrally with respect to the intended coverage area to minimize signal leakage to the outside. Only use directional antennas indoors in special cases when higher gain and directionality would be helpful and RF exposure limits will not be exceeded. • To avoid Signal Booster uplink overload and gain limiting, mount the indoor antennas away from areas where mobile subscribers frequently use their phones / radios, such as desks or dispatch areas. • To determine the quantity and locations of indoor antennas, measure Received Signal Strength Indication (RSSI) using DM Tool software to determine areas of weak signals. These are the approximate areas where indoor antennas may be needed. • Be aware that the signal from an indoor antenna, in most cases, can be expected to penetrate approximately two standard sheet rock walls to reach users. If the signal must travel through more than two walls, or if the walls are made of materials other than sheet rock, it may be necessary to split the available signal and add more antennas.

The Digital Signal Booster may come in one out of two versions: a 32 narrow-band filters version or an up-to-8 adjustable-bandwidth filters version. It is even possible to have both versions in one device so that the user can choose either of them. Depending on which version is actually running, the main screen of the Westell Control Software will have a slightly different look. 1. Turn on the Digital Signal Booster, connect computer to Signal Booster through Ethernet or USB cable, and run Westell Control Software. It is recommend to turn off the power amplifiers. PA OFF in narrow-band version WESTELL.COM ©2017 Westell Technologies 1.877.844.4274 July 2018; Doc No. VHF Signal Booster UM RA Page 42 of 95 VHF Product Manual July 2018, Rev B PA OFF in adjustable bandwidth version 2. Setup desired channel frequencies. Since Westell Signal Booster is channel selective, user has to know what frequencies are used in base station. Narrow-band filter frequency settings Program frequencies and bandwidths Frequency and Bandwidth settings 3. Turn on UL and DL power amplifiers, and check that any alarm indicator is active. WESTELL.COM ©2017 Westell Technologies 1.877.844.4274 July 2018; Doc No. VHF Signal Booster UM RA Page 43 of 95 VHF Product Manual July 2018, Rev B TURN ON POWER AMPLIFIERS PA ON in narrow band version TURN ON POWER AMPLIFIERS PA ON in adjustable bandwidth version 4. Setup desired operating gain using FCS. UL and DL chain are independent, so both values must be set. To set DL band gain is recommended that AGC works around 3dB in each channel, in this way, maximum output power is achieved. 5. Set up squelch settings. Controls are independent in UL and DL bands. Typical values for UL are 110dBm for squelch threshold. For DL, recommended value for squelch threshold is minimum level received in any active channel minus 10dB.

For narrow band filters version, setup desired filter bandwidth, depending on presence of adjacent channels. In principle, recommended bandwidth filter is 90KHz due to its low delay, but if adjacent signal is detected, narrow filters can be used. Spectrum analyzer of FCS can be used to know rejection to undesired signals. It is recommend that adjacent channels output power be, at least, 10dBc lower than useful carrier.
