Let’s Talk About Scanstrut LMB-EXTSHORT 25.5″ Extension Kit f/LMB Mounting Pole
The Scanstrut LMB-EXTSHORT 25.5″ Extension Kit f/LMB Mounting Pole is a specialized piece of marine hardware designed to elevate your GPS and VHF antennas above radar units. Manufactured by Scanstrut, this extension kit offers a simple and robust solution for optimizing antenna placement on boats, ensuring clear signal transmission and reception. This is particularly valuable in crowded marine environments where interference can be a real problem.
As someone who’s spent years fitting out vessels with communications and navigation gear, I’ve seen firsthand the challenges of antenna placement. When upgrading a client’s radar system on their fishing trawler, I realized the existing VHF antenna was creating significant interference. The Scanstrut LMB-EXTSHORT 25.5″ Extension Kit presented itself as the ideal solution to raise the VHF antenna clear of the radar dome.
Unboxing the kit revealed a well-machined, powder-coated aluminum extension pole, a joiner piece, and a small hardware kit. The construction felt robust and marine-grade, fitting with Scanstrut’s reputation for quality. The black color was also a plus, blending seamlessly with most existing radar mounts.
Alternatives considered included fabricating a custom extension from stainless steel tubing, or using generic mounting brackets. However, neither offered the integrated design and guaranteed compatibility of the Scanstrut kit. Other extension kits existed, but this specific model’s length and design were ideal for the limited space available on the trawler’s cabin top.
My first impression was positive; the kit exuded quality and thoughtfulness in its design. It seemed like a simple, effective solution to a common problem, and I was excited to see it in action.
Real-World Testing: Putting Scanstrut LMB-EXTSHORT 25.5″ Extension Kit f/LMB Mounting Pole to the Test
First Use Experience
The initial test took place during the installation on the fishing trawler, a 45-foot steel-hulled vessel operating in the Puget Sound. The conditions were typical for the area – damp, with a light chop on the water and a constant threat of rain. The primary goal was to elevate the VHF antenna to reduce interference with the newly installed radar system.
The installation process was relatively straightforward; the extension kit attached seamlessly to the existing Scanstrut LMB mounting pole and radome cradle. The included joiner piece was well-machined and provided a secure connection. No unexpected issues arose during the initial install; the product performed precisely as advertised.
Extended Use & Reliability
After several months of use, the Scanstrut LMB-EXTSHORT 25.5″ Extension Kit has held up remarkably well. There are no signs of corrosion or degradation, even with constant exposure to salt spray and harsh weather conditions. The powder coating remains intact, and the connection points are still solid.
Maintenance has been minimal, involving only occasional rinsing with fresh water to remove salt buildup. Compared to previous experiences with less robust mounting solutions, the Scanstrut kit has far exceeded expectations in terms of durability and reliability. This is a product that you install and forget about, which is exactly what you want on a working vessel.
Breaking Down the Features of Scanstrut LMB-EXTSHORT 25.5″ Extension Kit f/LMB Mounting Pole
Specifications
- The Scanstrut LMB-EXTSHORT 25.5″ Extension Kit is designed as an extension for the Scanstrut LMB Mounting Pole. It elevates antennas above the radar, reducing interference and optimizing signal transmission.
- It measures 0.6 meters (approximately 25.5 inches) in length. This provides a significant vertical separation between the radar and antenna.
- The kit includes a joiner and fastening kit. This ensures a secure and stable connection to the existing LMB Mounting Pole.
- It is constructed from marine-grade 316 stainless steel. This provides exceptional corrosion resistance in harsh marine environments.
