Frequently Asked Questions
Q: Can I use the MBM15 for UHF CB antennas or only marine VHF antennas?
A: The MBM15 is designed specifically for marine VHF antennas (156-163 MHz) in the AWM200/300/400 series ONLY. It is NOT compatible with UHF CB antennas (476-477 MHz) due to different mounting configurations, frequency specifications, and connector requirements. Marine VHF and UHF CB are completely different radio systems: Marine VHF is for marine communication and safety on water, while UHF CB is for land-based vehicle communication. If you need UHF CB antenna mount, consider MBM20 or MBM25 models designed for vehicle UHF applications.
Q: What's the difference between AWM200, AWM300, and AWM400 antennas and which should I choose?
A: The AWM series marine antennas differ primarily in height and gain characteristics: AWM200 is shorter antenna for smaller boats or low-profile installations; AWM300 is medium height providing balanced performance for most recreational boats; AWM400 is taller antenna providing maximum range for larger vessels or offshore use. The MBM15 mount accommodates all three with colour-coded identification tags helping match mount to appropriate antenna. Choose antenna based on: boat size and type, typical operating distance from shore, bridge clearance requirements, and desired communication range. Taller antennas provide better range but require more clearance.
Q: Does the MBM15 include the marine antenna or do I need to purchase it separately?
A: The MBM15 is an antenna mount with cable and connectors - the marine VHF antenna is NOT included and must be purchased separately from AWM200, AWM300, or AWM400 series. This mount is specifically designed to work ONLY with these three Uniden marine antenna models. When purchasing antenna separately, choose appropriate model (AWM200/300/400) based on your boat size and communication range requirements. The colour-coded identification tags on the mount help verify correct antenna matching during installation.
Q: Why does the MBM15 have a round base instead of square base like vehicle mounts?
A: The round base design is specifically engineered for marine mounting applications where round bases are standard for: (1) mounting on boat gunwales (rail edges) with curved surfaces; (2) T-top installations with round tube structures; (3) marine rail brackets designed for round base mounts; (4) compatibility with marine industry standard mounting configurations. Marine environments differ from vehicle roof racks (which use square bases), requiring different mounting geometry for secure installation on boat structures. The round base provides proper marine mounting while the ratchet fold-down accommodates bridge clearance - a marine-specific requirement not needed for vehicle applications.
Q: How does the fold-down feature work for bridge clearance?
A: The ratchet fold-down mechanism allows controlled lowering of marine antenna for situations requiring reduced height: (1) Bridge clearance - lower antenna when passing under bridges or overpasses on inland waterways; (2) Marina storage - reduce height when docked in covered slips or storage facilities; (3) Trailer transport - fold down for towing boat on trailer under bridges or parking structures; (4) Storm preparation - lower antenna during severe weather to reduce wind resistance. The ratchet provides controlled positioning preventing free-swinging or uncontrolled movement, while double hinge allows precise angle adjustment. This feature is essential for boats operating in areas with bridges or requiring variable antenna height for different operating conditions.
