The square base provides secure stable mounting platform on various surfaces including roof racks, bull bars, or mounting brackets. Pre-fitted with 5 metres high-quality coaxial cable eliminates need for separate cable purchase and simplifies installation, while included FME plug connector and PL259 adaptor ensure universal compatibility with different antenna and radio connector types. The rain cap keeps connections clean, protected, and dry preventing moisture ingress and signal degradation. Complete ready-to-install package ideal for 4WD vehicles, commercial trucks, boats, caravans, and mobile applications requiring professional antenna mounting with weather protection.

Important Notes:

Antenna NOT Included: This is an antenna mount with cable and connectors. UHF antenna must be purchased separately. Compatible with standard UHF antennas with appropriate thread fittings.

Mounting Surface Required: Square base requires suitable mounting surface (roof rack, bull bar, bracket) with appropriate fasteners. Mounting hardware to vehicle not included - specific to mounting location.

5m Cable Length: Pre-fitted with 5 metres coaxial cable. Verify this length is sufficient for your installation routing from antenna to radio location. Cable cannot be easily lengthened or shortened.

Technical Specifications

Frequently Asked Questions

Q: Does the MBM25 include the UHF antenna or do I need to purchase it separately?

A: The MBM25 is an antenna mount with cable and connectors - the UHF antenna is NOT included and must be purchased separately. This mount is designed to work with standard UHF antennas featuring compatible thread fittings (most common UHF antennas). When purchasing antenna separately, verify thread compatibility and mounting requirements. The included PL259 adaptor accommodates most common UHF antenna base fittings. We can recommend compatible antennas if needed - contact us for antenna recommendations matching your vehicle and application.

Q: Can I use the 5m pre-fitted cable or do I need to replace it with longer cable?

A: The 5 metres coaxial cable is permanently pre-fitted to the mount and cannot be easily replaced or extended without cutting and re-terminating connections (not recommended as it affects warranty and signal quality). Before purchasing, measure routing distance from intended antenna mounting location to radio location ensuring 5m is sufficient. Typical routing (roof mount to interior radio) usually requires 4-6m. If your installation requires longer cable, consider alternative mounting locations closer to radio or different mount with longer cable option.

Q: What's the advantage of the ratchet fold-down feature?

A: The ratchet fold-down mechanism provides significant practical benefits: (1) lower antenna for garage entry without removing antenna entirely; (2) fold down for automatic car washes preventing antenna damage; (3) reduce height for low-clearance obstacles (parking structures, drive-throughs); (4) storage position when vehicle parked reducing vandalism risk or wind resistance; (5) controlled positioning with ratchet prevents free-swinging or uncontrolled movement. The double hinge allows folding backward or forward depending on installation. This feature particularly valuable for daily drivers entering garages regularly compared to permanent fixed mounts.

Q: What are FME and PL259 connectors and why are both included?

A: These are different connector standards used in radio and antenna connections. FME (For Mobile Equipment) is a screw-on connector commonly used on modern UHF radios and marine radios - the FME plug connects to radio end of cable. PL259 (also called UHF connector) is a larger threaded connector commonly used on antenna bases and some older radios - the PL259 adaptor allows antenna connection. Including both ensures universal compatibility: FME for radio connection, PL259 adaptor for antenna connection. This eliminates need to source separate adaptors matching your specific radio and antenna combination.

Q: Where should I mount the MBM25 on my vehicle?

A: Common mounting locations include: (1) Roof rack crossbars - popular for 4WD vehicles, provides optimal antenna height and 360° signal; (2) Bull bar - convenient mounting using bull bar brackets, good height and accessibility; (3) Tray/canopy - for utes/trucks with rear tray, mounts securely to canopy or tray rails; (4) Rear bumper bar - alternative location for vehicles without roof racks. Choose location considering: cable length reaches radio (5m limit), minimal obstructions for signal, secure mounting surface available, fold-down mechanism operates freely, and personal access for maintenance. Professional installers can assess optimal location for your specific vehicle.
