VHF (150.8–162 MHz) Magnetic-Mount External Whip Antenna & Adapter Kit
Genuine Motorola Solutions Original VHF (150.8–162 MHz) magnetic-mount whip antenna kit complete with heavy-duty magnetic base, coaxial lead, and RF adapter for rapid no-drill vehicle deployments.
The Motorola HAD8437A is an authentic original equipment manufacturer (OEM) magnetic-mount external antenna kit engineered to extend the communication range of two-way radios operating in the VHF (150.8–162 MHz) frequency band. Sourced directly from our verified inventory of Two-Way Radio Antennas, this complete kit includes an 18-inch VHF (150.8–162 MHz) whip antenna, a magnetic mount base with attached coaxial cable, and an RF connector adapter—giving fleet managers, public works crews, security teams, and temporary command vehicles an immediate external antenna solution without drilling permanent holes in vehicle sheet metal.
Operating a two-way radio inside an enclosed vehicle subjects RF signals to severe attenuation from steel roof pillars and metallic window coatings. Mounting the Motorola HAD8437A onto the exterior metal roof uses the vehicle body as an effective RF ground plane, dramatically improving both outbound transmit reach and inbound receiver sensitivity across VHF (150.8–162 MHz) channels. Built with a slim 0.13-inch diameter stainless-steel whip and a high-retention magnetic base, the assembly resists wind buffeting at highway speeds and withstands harsh outdoor exposure in accordance with DoD Standards (MIL-STD-810) and workplace fleet safety guidelines under OSHA Standards.
Key Features & Benefits
-
Complete 3-Piece Ready-to-Deploy Kit: Ships with the 18-inch VHF (150.8–162 MHz) whip antenna, heavy-duty magnetic mount base with coax cable, and RF connector adapter in one package.
-
Tuned for VHF (150.8–162 MHz) High-Band: Precision-matched across 150.8–162 MHz to deliver low VSWR, efficient power transfer, and crisp omnidirectional signal coverage.
-
No-Drill Magnetic Mounting: Installs and removes in seconds on steel vehicle roofs or trunk lids—ideal for leased fleets, unmarked vehicles, rental cars, and rapid incident response.
-
Overcomes In-Cabin Signal Loss: Moves the radiating whip outside the vehicle's metal frame to eliminate cabin shielding and boost effective communication range.
-
18-Inch Flexible Whip Element: Low-profile 18-inch (457.2 mm) height provides reliable quarter-wave VHF performance while maintaining clearance under standard parking structures and garages.
-
Dedicated RF-Only Design: Focused purely on VHF (150.8–162 MHz) voice/data RF performance without integrated GPS circuitry (
Integrated GPS: No).

Frequently Asked Questions
What comes inside the Motorola HAD8437A kit?
The Motorola HAD8437A ships as a complete 3-piece external antenna kit containing the 18-inch VHF (150.8–162 MHz) whip antenna, the magnetic mount base with attached coaxial lead, and an RF connector adapter for connecting to compatible VHF radio ports.
What frequency range does the Motorola HAD8437A cover?
This antenna is factory-tuned for the VHF (150.8–162 MHz) band. Verify that your radio's programmed transmit and receive frequencies fall within 150.8–162 MHz before deploying to ensure optimal VSWR and transmitter protection.
Does the Motorola HAD8437A include a built-in GPS receiver?
No. The HAD8437A is a dedicated VHF (150.8–162 MHz) voice and data RF whip antenna (Integrated GPS: No) and does not contain an integrated GPS patch element.
Where should I place the magnetic mount on my vehicle for best performance?
For maximum range and proper ground-plane coupling, place the magnetic mount near the center of a flat, clean metal roof panel away from roof racks, lightbars, and sunroof glass. Avoid mounting on aluminum, fiberglass, or composite body panels, as magnetic bases require a ferrous steel surface to adhere securely and establish an RF ground plane.
Can I use this antenna with UHF (400–512 MHz) or 700/800 MHz radios?
No. Because the whip length and matching network are tuned specifically for VHF (150.8–162 MHz), using it on UHF or 700/800 MHz radios will result in high VSWR, poor range, and potential transmitter final-stage damage.
