Note: All specification shown are subject to change without notice. General Frequency Range: Dual Band VHF 136-174MHz & UHF 400-520MHz FM Radio Frequency Range: 65Mhz-108Mhz Channel Capacity: 128 Channel Spacing: 25KHz/12.5KHz Antenna Impedance: 50Ω Microphone Impedance: 600Ω Operating Voltage: 7.4V DC Frequency Stability: ±2.5ppm Battery: 2200mAh(Polymer Li-ion) Compatible With American Military Standard(Mil-STD-810C/D/E) Transmitter (EIA-RS 316B STANDARD) RF Power Output: 8W Modulation Type: FM Modulation Sensitivity: <15μV Modulation Distortion: ≤3% Max Freq Deviation: <5KHz Occupied Bandwidth: ≤16KHz Modulation Feature: ±3dB Spurious Radiation: ≤7.5μW Adjacent Channel Power: ≤-65dB Receiver Sensitivity(12db SINAD): ≤0.15μ(12dB S/N) Squelch Sensitivity: ≤0.1μV Audio Power output: 1W/16Ω Audio Respond: -6 Operation Bandwidth: >5KHz Co-channel Rejection: ≥-8dB Blocking: ≥85dB Adjacent Channel Selectivity: ≥65dB Standby Current: 60mA,15mA Spurious Rejection: ≥60dB Intermodulation Resistance: ≥60dB IP stands for &x27;Ingress Protection&x27; An IP number is used to specify the environmental protection of enclosures around electronic equipment. These ratings are determined by specific tests. The IP number is composed of two numbers, the first referring to the protection against solid objects and the second against liquids. The higher the number, the better the protectionces First Number 0 - No protection (Sometimes X) 1 - Protected against solid objects up to 50mm3 2 - Protected against solid objects up to 12mm3 3 - Protected against solid objects up to 2.5mm3 4 - Protected against solid objects up to 1mm3 5 - Protected against solid objects up to 1mm3 6 - Totally protected against dust Second Number 0 - No protection (Sometimes X) 1 - Protection against vertically falling drops of water (e.g. condensation) 2 - Protection against direct sprays of water up to 15 degrees from vertical 3 - Protection against direct sprays of water up to 60 degrees from vertical 4 - Protection against water sprayed from all directions - limited ingress permitted 5 - Protected against low pressure jets of water from all directions - limited ingress permitted 6 - Protected against low pressure jets of water, limited ingress permitted (e.g. ship deck) 7 - Protected against the effect of immersion between 15cm and 1m 8 - Protected against long periods of immersion under pressure |
