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 straightforward antenna mounting with weather protection at economical price point.

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.

Single Hinge vs Double Hinge: MBM20 features single hinge design compared to MBM25's double hinge. Single hinge provides simpler operation and lower cost while maintaining ratchet fold-down capability and reliable mounting.

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: What's the difference between the MBM20 (single hinge) and MBM25 (double hinge) mounts?

A: The primary difference is hinge configuration: MBM20 features single hinge providing one pivot point for forward/backward antenna positioning, offering simpler operation and more economical price. MBM25 features double hinge with two pivot points allowing more complex angle adjustments and positioning flexibility. Both include: ratchet fold-down mechanism, 5m pre-fitted cable, FME connector, PL259 adaptor, rain cap, and square base. Choose MBM20 for straightforward reliable mounting at lower cost, or MBM25 if you need additional positioning flexibility for specific installation challenges.

Q: Does the MBM20 include the UHF antenna or do I need to purchase it separately?

A: The MBM20 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 the single hinge provide enough adjustment for optimal antenna positioning?

A: Yes! The single hinge with ratchet mechanism provides adequate adjustment for most standard installations. The single pivot point allows forward/backward positioning for optimal antenna angle, while the ratchet maintains secure position without slipping. For typical roof rack or bull bar mounting, single hinge adjustment is sufficient for proper antenna orientation. The simpler single hinge design actually benefits many users with: easier operation without complex adjustment procedures, fewer moving parts for improved reliability, and straightforward positioning that's easier to set and maintain. Only specialized installations requiring extreme angle flexibility need double hinge complexity.

Q: Is the 5m cable length the same on both MBM20 and MBM25 models?

A: Yes, both MBM20 (single hinge) and MBM25 (double hinge) include the same 5 metres pre-fitted coaxial cable. The cable length is standardized across both models. Before purchasing either model, measure routing distance from intended antenna mounting location to radio location ensuring 5m is sufficient. Typical routing from roof mount to interior radio usually requires 4-6m. If your installation requires longer cable, consider alternative mounting locations closer to radio. The cable cannot be easily extended without affecting signal quality and voiding warranty.

Q: Where should I mount the MBM20 on my vehicle for best results?

A: Optimal mounting locations for the MBM20 include: (1) Roof rack crossbars - most popular for 4WD vehicles, provides best antenna height and 360° signal coverage; (2) Bull bar top rail - convenient mounting using bull bar brackets, good height and easy installation access; (3) Rear tray/canopy rails - for utes/trucks with rear tray, secure mounting to canopy or tray cross bars; (4) Rear bumper bar - alternative for vehicles without roof racks. Consider: 5m cable reaches radio location, minimal signal obstructions, secure mounting surface available, fold-down mechanism operates without interference, and easy access for maintenance. The single hinge operates in forward/backward direction, so mount where this movement accommodates garage entry or clearance needs.
