Product Description
PCTEL MHB5800 VHF 144–174 MHz 3 dB Gain 5/8 Wave NMO Antenna
The PCTEL MHB5800 is a field-tunable VHF mobile antenna for vehicle-mounted two-way radio systems. Its base-loaded 5/8 wave design provides a manufacturer-rated 3 dB gain, with tuning available within 144–174 MHz. A stainless steel whip and tapered coil housing suit commercial vehicle installations.
Before ordering: This listing is for the MHB5800 antenna without a spring. The NMO mount, coaxial cable and radio connector are sold separately. The antenna must be tuned for your operating frequencies.
Key Features
- Field-tunable VHF design: Adjust for operating frequencies within 144–174 MHz.
- 3 dB rated gain: A gain antenna option for mobile VHF communication systems.
- 200-watt maximum power rating: Suitable for installations operating within the antenna’s power limit.
- Stainless steel whip: Durable construction for vehicle use.
- Tapered coil housing: Helps protect the loading coil from moisture.
- NMO mounting: Mates with standard 1-1/8-inch–18 thread antenna mounts.
Benefits for Vehicle Radio Systems
The MHB5800 gives installers a tunable antenna option for a defined VHF channel group. Proper tuning, mounting location and coaxial cable selection help the complete radio system perform effectively. Actual communication range depends on terrain, obstructions, antenna height and the equipment at both ends of the connection.
Ideal Applications
- Commercial fleet and service vehicles
- Transportation and maintenance operations
- Utility and industrial vehicles
- VHF railroad support vehicles when tuned for their assigned channels
Compatibility and Installation
Select the MHB5800 for a VHF radio system whose operating frequencies fall within its 144–174 MHz tuning range. Compatibility depends on the operating frequencies, radio power, antenna mount, coaxial cable and radio-side connector.
Tuning range is not instantaneous bandwidth. The 144–174 MHz specification means the antenna can be adjusted within that range. It does not mean one adjustment provides the same match across the entire band. Follow the manufacturer’s tuning instructions and verify the installed antenna match across the channels you use.
For magnetic mounting, choose an NMO magnetic mount specifically rated to support this antenna’s height and mechanical load. Confirm the mounting surface, cable routing, connector and vehicle clearance before installation.

Frequently Asked Questions
Does the MHB5800 need tuning?
Yes. It is field tunable within 144–174 MHz and should be adjusted for the frequencies used by your radio system.
Can it be used for railroad frequencies?
Frequencies from 159.570 to 161.565 MHz fall within its tuning range. Tune and verify the antenna across the required channels before transmitting.
Does it include a magnetic mount?
No. Select a compatible NMO mount separately, along with the appropriate cable and radio connector.
Does this model include a spring?
No. MHB5800 is the version without a spring. If your installation requires a spring-equipped antenna, ask HiTech Wireless about the appropriate model before ordering.
Will a longer antenna always provide more range?
No. Antenna design, tuning, mounting position and surrounding terrain all affect coverage. Choose an antenna for the complete installation rather than length alone.
