EhubAmerica EPC-150V2 VHF Helical Antenna 146-174 MHz Stud

The EhubAmerica EPC-150V2 is a VHF helical replacement antenna engineered for Motorola portable radios operating across the 146–174 MHz band, with an optimized center frequency of 150 MHz and a tuned operating range of 150–164 MHz. Built around a durable urethane sleeve and ABS cap, the antenna delivers a unity-gain omnidirectional radiation pattern with vertical polarization and a 50-ohm impedance match, making it a direct, field-ready replacement for worn or damaged stock antennas. At 149 ± 3 mm in total length, it preserves the compact profile essential for portable radio operation in commercial, professional, and field communications environments.

Key features & benefits

• VHF Frequency Coverage: 146–174 MHz — Supports the full 146–174 MHz VHF band with a center frequency of 150 MHz and an optimized tuned range of 150–164 MHz, covering the most common commercial and professional VHF channel allocations.
• Low VSWR for Efficient Power Transfer — A VSWR of less than 2.0 across the operating range ensures minimal reflected power and maximum energy transfer between the radio's transmitter and the antenna, preserving range and protecting the radio's RF output stage.
• Omnidirectional, Vertically Polarized Radiation Pattern — The omnidirectional pattern radiates evenly in all horizontal directions, eliminating the need to orient the antenna toward a repeater or base station—critical for mobile users in unpredictable field environments.
• 50-Ohm Impedance — Matched to the standard 50-ohm RF architecture of Motorola portable radios, ensuring compatibility with the radio's internal transmission line without the need for additional impedance matching hardware.
• Helical Design with Urethane Sleeve and ABS Cap — The helical winding housed in a urethane sleeve provides mechanical flexibility and impact resistance, while the ABS cap contributes structural rigidity—together extending antenna service life in demanding daily-use conditions.
• Stud Connector Interface — Utilizes a stud connector interface consistent with Motorola portable radio antenna port standards, enabling straightforward tool-free replacement in the field.
• Compact 149 mm Form Factor — At 149 ± 3 mm total length, the antenna maintains the low-profile dimensions expected of a portable radio antenna, avoiding bulk or imbalance during extended carry and use.
