Product Information For Bolton Single Low Profile Dome Antenna Expansion Kit 50 Ohm

Bolton Single Rondo Low-Profile Antenna Expansion Kit – Expand Your Indoor Coverage with Style and Power

Need to boost cellular signal in more rooms or on another floor? The Bolton Single Rondo Low-Profile Antenna Expansion Kit is the sleek solution for extending indoor coverage – perfect for South African homes, offices, warehouses, and commercial buildings where one antenna simply isn’t enough.

What's in the Kit:

The Bolton Single Rondo Low-Profile Antenna Kit, the indoor antenna expansion kit featuring:

  • Bolton Rondo 4G Low-Profile Antenna (ceiling mount)

  • 2-way splitter

  • LMR400 (15m and 1m) for indoor antenna installation, pre-crimped with N-Male connectors

Why choose a Rondo Low-Profile 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 coverage throughout. This all-in-one expansion kit includes a professional-grade Rondo 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 sleek, low-profile ceiling-mounted design, the Rondo antenna blends seamlessly into any environment while radiating signal in a full 360-degree pattern. It ensures consistent coverage across open spaces, hallways, and rooms – perfect for modern interiors where discreet design and strong performance are equally important.

Key Benefits: The Bolton Rondo Low-Profile 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 a clean, professional finish.

This kit is fully compatible with all 50-ohm cell signal boosters and installs easily with minimal fuss. Each component is built for low-loss, high-efficiency performance, delivering professional-grade coverage where it matters most.

Whether you're managing a growing office, upgrading your warehouse, or solving patchy reception at home, the Bolton Single Rondo Low-Profile Antenna Expansion Kit is your go-to solution for seamless indoor signal coverage.

Installation Note: Expanding your coverage is simple – just mount the Rondo Low-Profile 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.

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 strong, usable signal across your entire environment.
