Frequency Range：144 - 148 MHz (VHF) and 430 - 450 MHz (UHF)
Gain：Typically around 2.15 dBi at 144 MHz and 5.0 dBi at 430 MHz, which may vary by model.
Impedance：50 Ω
VSWR：≤ 1.5
Maximum Input Power：Can be up to 200W for some models, while others may be 50W or 80W, etc.
Radiation Pattern：Omnidirectional, providing 360 - degree horizontal coverage for effective communication in all directions.
Polarization：Vertical polarization, which is common for mobile radio antennas and compatible with most base stations.
Connector Type：Common types include SMA, N - type, and PL259, etc.
Length：Varies by model, can be as short as about 39 cm or as long as over 70 cm.
Mounting Type：Often includes magnetic mount for easy installation on vehicles, and there are also NMO (No - Mounting - Hole) mounts for some models, which can be installed through vehicle roofs without drilling holes.
