The WAPS beacon is a powered by power system, and is provided with four 12 volt batteries (providing 48VDC) approved for use in telecommunications equipment. WAPS Operating Temperature: -40 Deg C to +50 Deg C operating Storage temperature: -55 Deg C to +80 Deg C Humidity: 90% non-condensing. WAPS weight: 100 lbs. Power rating: 120VAC, 60Hz, 4 AMP 3 Equipment List: • NextNav WAPS Beacon • NextNav Power System • Antenna – Transmit Omni – GPS : L1 GPS (BL1R-A-XTB-1-FKM) • Cables – TX antenna cable: As per chart below: Main Feed Length Cable Type Jumper Top Jumper Bottom <50’ LDF4 (1/2”) None None 51’-130’ LDF5 (7/8”) None None 131’ -250’ LDF 7 (15/8”) ½” X10’ ½” X 6 ft – GPS antenna Cable: (not to exceed 100 feet) GPS cables are pre-fabbed and available in three lengths: 25’, 50’ and 100‘. The cable is an LMR 240 or equivalent (1/4”) and is pre-terminated with mating ends N male for connection to the beacon and TNC Male for the antenna end.

As a general rule on any monopole installations the TX antenna shall be attached to a 6 foot side arm mount, minimum distance away from the monopole unless the antenna extends above the monopole in its entirety. Likewise the antenna shall be kept a minimum distance of 6 feet from any other vertical structures on other types of towers. For roof tip installations, the TX antenna must extend above all parapet walls and penthouses on the roof top. This radio transmitter (FCC ID: A4P-100-0007-01) has been approved by FCC 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. This radio transmitter may only operate using a vertically polarized antenna with maximum gain of +8 dBi. To reduce potential radio interference to other users, the antenna gain should be so chosen that the effective radiated power (ERP) does not exceed 30 Watts. Antenna Type: Monopole Polarization: Vertical Maximum Gain: +8 dBi (maximum gain of antenna + cable loss is 0dBd) Following is a list of the possible antennas and antenna cables combinations.

This parameter will be used by the NOC to configure the radio output power. 4.2 Tune-up procedure not to exceed maximum TX Power A CSV file (configuration file) per transmitter are created by the NOC engineer based on the installation parameters such as line lengths, antenna type etc. To comply with FCC RF exposure requirements in Section 1.1307 of FCC Rules, the antenna used for this transmitter must be fixed-mounted on outdoor permanent structures with a separation distance of at least 77.5 cm from all persons.

Page 7 15-Nov-12 Page 7 of 7 The TX output power level setting is contained in the CSV file. The output power is adjusted by the ‘attenuation’ setting This value in the CSV file is calculated by a formula to set the output power (not to exceed 30W EIRP). The variables used in the calculation include PA Gain (Gpa), TX Antenna Gain (Gant), TX filter insertion loss (ILflt), internal cable loss (ILint), external cable loss (ILext), and transceiver output power (PTCVR). EIRP (W) = 10^((PTCVR - ILint + Gpa - ILflt - ILext + Gant) / 10) / 1000 4.3 GPS Receive Antenna GPS antenna should be installed such that it has clear view of sky. Ideally, you would keep the antenna close to the ground away from obstruction • Keep any horizontal blockage smaller than 10 degrees • Obstruction Clearance guideline – If it is 1 ft wide it should be at least 6 ft away – If it is 10 ft wide, it should be at least 60 ft. away. – If it is significantly less than 1 ft wide (like a guy wire, or a post) it should not cause any measurable effect. 4.4 Product information Modifications made to the product, unless expressly approved by NextNav, LLC could void the user’s authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device , pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.
