Proxicast X-Boom MIMO Antenna Mast Cross-Over Bracket Kit - Rugged

In this review the Proxicast X-Boom MIMO antenna mast cross-over bracket kit is evaluated for installers and hobbyists who need to add multiple antennas or accessories to a single pole. The bottom line: this kit is best for anyone who needs a sturdy, weatherproof way to mount two mast poles at a 90 degree angle and maintain consistent vertical height for MIMO setups. Its biggest strength is build quality and straightforward mountability, making it a reliable choice for towers, railings or flag poles when physical separation of antennas is required.

Key Features

• Cross-over mounting: Allows two antenna mast poles to be mounted at a true 90 degree angle so antennas can be separated physically for better performance.
• MIMO friendly: Lets multiple antennas be mounted horizontally at the same vertical height to preserve spatial diversity and reduce interference.
• Universal clamp fit: Accepts round or square poles from 1.25 to 2.0 in OD so it installs on a wide range of masts, posts, and railings.
• Accessory ready: Can support weather stations, lights, security cameras or small solar panels on outdoor flag poles or posts for flexible use.
• Durable hardware: Includes a heavy duty right-angle plate and mounting hardware that users describe as strong and well built for outdoor conditions.

Who It's For

The kit is aimed at radio, TV and wireless installers, amateur radio operators, and anyone adding additional antennas to an existing tower or mast. It works well for users who need reliable physical separation for MIMO arrays or who want to attach small accessories like cameras or lights to an existing pole.

It may be unnecessary for someone who only needs a single vertical mast or who requires specialized large-diameter mounting solutions, as the clamp range is limited to poles between 1.25 and 2.0 in OD. Those needing integrated pole sections or custom engineering for heavy loads should look elsewhere.

Pros & Cons

Pros

• Solid build quality and heavy duty plate provide a stable mounting point for multiple masts.
• Simple to attach to existing towers, masts or railings thanks to the crossover clamp design.
• Accepts both round and square poles within the documented size range for flexible installation options.

Cons

• Installation experiences are mixed for some users, so basic mechanical skills and proper alignment are recommended.
