Product Information For Bolton Single Dome Antenna Expansion Kit 50 Ohm

Bolton Single Dome Antenna Expansion Kit – Expand Your Indoor Coverage Where It Counts

Need to boost cellular signal in more rooms or on another floor? The Bolton Single Dome Antenna Expansion Kit is the smart solution for extending indoor coverage - ideal for South African offices, homes, offices, warehouses, and commercial buildings where one antenna isn’t enough to get the job done.

What's in the Kit: The Bolton Single Dome Antenna Kit, is the indoor antenna expansion kit featuring:

  • 4G Ceiling Mount Dome Antenna
  • 2-way splitter
  • LMR400 (15m and 1m) for an indoor antenna installation crimped with N-Male connectors

Why choose a Dome Expansion Kit? While your current booster setup may work well in one area, buildings with thick walls, split layouts, or multiple floors often need more than a single antenna to deliver reliable signal throughout. This all-in-one expansion kit includes a professional-grade dome antenna, ultra-low loss Bolton400 coaxial cable, and a 2-way splitter - everything you need to distribute boosted signal further indoors and eliminate frustrating dead zones.

With its discreet ceiling-mounted design, the dome antenna radiates signal in a 360-degree pattern, ensuring consistent coverage across open spaces, hallways, and rooms. Whether you’re covering a new wing, expanding operations, or just solving patchy reception, this kit delivers dependable indoor performance where it matters most.

Key Benefits: The Bolton Dome Expansion Kit makes it easy to scale your existing system without compromise. Add coverage in hard-to-reach zones, reduce dropped calls, and improve voice clarity and data speeds across your building — all while maintaining the integrity of your original installation.

This kit is fully compatible with all 50-ohm cell signal boosters and installs cleanly with minimal fuss. The included components are built to deliver low-loss, high-efficiency performance for reliable, professional-grade coverage.

Whether you're managing a growing office or boosting bars in your home’s dead spots, the Bolton Single Dome Antenna Expansion Kit is your go-to solution for complete indoor signal coverage.

Installation Note: Expanding your coverage is simple - just mount the dome antenna to the ceiling in your target area, run the Bolton400 cable back to your splitter, and integrate it into your existing booster system. You’ll be up and running with improved coverage in no time. It’s a clean, scalable upgrade that pays off in better connectivity across every corner of your space.

If your building has tricky layouts, multiple floors, or thick walls blocking signal, this kit gives your booster the reach it needs - turning isolated coverage into full, usable signal across your entire environment.
