H4JVT-3A130-F25kHz AM TRANSMITTER

User's Guide The VT-3A130 Transmitter is a synthesized multichannel AM transmitter designed to interface with the MT-3 Repeater Systems, while still maintaining MT-2 system compatibility. Both MT-3 systems are characterized by dependable low maintenance performance under the most severe environmental conditions. In addition, all units are burnt-in for 24 hours and are accompanied by a complete test report. The VT-3A130 Transmitter operates in the 118 - 137 MHz aviation band. The transmitter’s frequency stability is controlled by an OST-3A138 AM Enhanced Synthesizer. The Synthesizer module can be programmed for up to 16 channels. A channel programmer can preprogram the first 15 channels; channel 16 can be programmed from the front panel and channel 1 can be programmed by the four BCD switches located on the MT-3 AM Transmitter Main Board. The VT-3A130 modular transmitter family is compatible with all Daniel’s subrack and base station enclosures.

Applicant: Daniel Electronics Ltd Page 1 of 2 FCC ID: H4JVT-3A130-F Report #: 2283AUT6 FCC RF Exposure Requirements General information : FCC ID: H4JVT-3A130-F Device category: Mobile per Part 2.1091 Environment: Controlled Exposure Fixed devices that operate under Part 87 of this chapter are subject to routine environmental evaluation for RF exposure prior to equipment authorization or use if they operate at frequencies of 1.5 GHz or below and their effective radiated power (ERP) is 1.5 watts or more. However, compliance with the power density limits of 1.1310 is not required. Antenna: The manufacturer does not specify any antenna to be used with this device. This device has provisions for operation in a fixed location. Configuration Antenna p/n Type Max. Gain (dBi) Fixed Any omni 9 Operating configuration and exposure conditions: The conducted output power is 3 watts. Typical use qualifies for a maximum duty cycle factor of 50%. The manufacturer also markets this device only for occupation use. But because of a fixed structure and not being able to control exposure in all cases we have used the uncontrolled expose limit. - Part 2.1091 states that devices are excluded from routine evaluation if the EIRP is less than 2.46Watt (or 1.5WERP). - Fixed Operation: The maximum antenna gain that can be used is 9 dBi. A coaxial cable of the type RG 58 has a loss of 1dB for a length of 15 feet. MPE Calculation : The minimum separation distance is calculated as follows: The limit for uncontrolled exposure environment below 300 MHz is fixed at 0.2 mW/cm 2 . Applicant: Daniel Electronics Ltd Page 2 of 2 FCC ID: H4JVT-3A130-F Report #: 2283AUT6 Channel frequency: 118 to 137 MHz The conducted power output is 3 watt. The coax loss was taken as 1 dB. Antenna gain was taken as 9 dBi 50% talk time in 30 minutes which reduces the power to 1.5 Watts in the formula below. The value for S is fixed at 0.2 mW/cm 2 which in the formulas below is shown as 300/1500. required for compliance Rinches24.16= distance in centimeters R61.366= Rinches R 2.54 := R Po Gn⋅() 4π⋅S⋅ () := Gn6.31= mW cm 2 S0.2= Gn10 G 10 := gain numeric 1500 for uncontrolled exposure gain in dBi G8= S f 1500 := GdBd2.15+1−:= Frequency in MHz f300:= antenna gain dBd6.85:=mWattsPo1500:= Conclusion: The device complies with the MPE requirements by providing a safe separation distance of 62 cm between the antenna, including any radiating structure, and any persons when normally operated . Proposed RF exposure safety information to include in User’s Manual : “FCC RF Exposure Requirements: CAUTION: The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. This device is approved with emissions having a source-based time-averaging duty factor not exceeding 50%. Antenna Installation: - Antennas used for this transmitter must not exceed an antenna gain of 9 dBi with a minimum cable loss of 1dB. - Failure to observe these restrictions will result in exceeding the FCC RF exposure limits.
