The PCTEL K50494 VHF Rear Mount Car Antenna is a high-quality, vehicle-mounted antenna designed for VHF (Very High Frequency) two-way radio communication. This antenna is ideal for public safety, commercial fleets, and utility vehicles, providing reliable omnidirectional coverage with a durable rear-mount design for added protection and stability.

The PCTEL K50494 is a high-performance mobile antenna engineered for vehicular VHF communication. It features a rear-mount design, meaning it is installed on the trunk or rear body panel of a vehicle, rather than the center of the roof. This placement helps reduce wind resistance and potential damage while maintaining strong radio signal performance.

It is commonly used by law enforcement, emergency response teams, commercial fleets, construction vehicles, and agricultural machinery, ensuring clear and reliable communication in various environments.

🔹 Frequency Range: VHF 150-174 MHz (supports standard VHF two-way radio bands)
🔹 Antenna Type: Quarter-wave or half-wave, depending on configuration
🔹 Gain: 0 dBi to 3 dBi (unity gain for mobile applications)
🔹 Impedance: 50 ohms (industry standard for RF communication)
🔹 Polarization: Vertical (ensures optimal ground-based radio communication)
🔹 Radiation Pattern: Omnidirectional (provides 360-degree horizontal signal coverage)
🔹 VSWR (Voltage Standing Wave Ratio): Typically ≤ 2:1 (ensures efficient signal transmission)
🔹 Connector Type: NMO (New Motorola Mount) – Standardized mount for mobile antennas
🔹 Cable Type: RG-58/U or RG-316, depending on model variation
🔹 Cable Length: Typically 12-17 feet (3.6-5.2 meters)
🔹 Power Handling: Up to 100W, supporting high-power radio transmitters
🔹 Mounting Type: Rear-mount with NMO base, designed for vehicle trunk or rear panel installation
🔹 Material & Durability:

• Flexible whip or rigid stainless steel construction
• Weatherproof and corrosion-resistant materials for long-term durability
  🔹 Operating Temperature: -40°C to +85°C, ensuring performance in extreme conditions
