Directional antenna LIBOX LB2100 — 36-element VHF + UHF DVB-T combo with LTE filter

Directional LIBOX LB2100 antenna is a combined 36-element VHF + UHF design for terrestrial DVB‑T reception. The antenna integrates elements tuned for both VHF and UHF bands in a single directional array, enabling reception of digital terrestrial television channels from distant transmitters. It is intended for rooftop or mast installation and includes an LTE filter to reduce interference from nearby mobile networks, improving signal stability and reducing pixelation or dropouts on DVB‑T broadcasts.

Advantages

The LIBOX LB2100 combines VHF and UHF reception in one directional antenna, simplifying installation where both bands are used. Its 36-element design provides increased gain and improved directivity compared with simple dipole sets, helping to capture weaker multiplexes. The built-in LTE filter attenuates out-of-band signals from cellular transmitters, which helps maintain clean reception in areas with strong mobile coverage. The antenna is suitable for rooftop or mast mounting and can be aligned to a specific transmitter to maximize performance.

Suitable for

• Residential rooftop DVB‑T installations where VHF and UHF channels are both required
• Small commercial buildings needing stable terrestrial TV reception
• Locations with moderate to long-range reception where directional gain is beneficial
• Areas with nearby mobile networks where LTE filtering is needed to reduce interference

Key specifications

• Frequency coverage: combined VHF and UHF bands for terrestrial TV reception
• Antenna type: directional 36-element array for improved gain and directivity
• Interference suppression: integrated LTE filter to reduce mobile signal ingress
• Mounting: designed for rooftop or mast installation with adjustable alignment
• Connector: standard TV coaxial output for connection to DVB‑T tuners and set-top boxes

How to use

Mount the LIBOX LB2100 on a suitable rooftop mast or pole at a height clear of obstructions, and orient the antenna toward the intended terrestrial transmitter. Connect the antenna coaxial output to the DVB‑T receiver or TV tuner using quality coax cable and connectors. After physical installation, perform a channel scan on the receiver to detect available multiplexes. If reception problems persist, fine-tune the antenna direction and check cable terminations and grounding.

Usage recommendations

For best results, place the antenna as high as practical and ensure a solid mechanical mount. Use shielded coaxial cable with correct impedance and maintain proper grounding to reduce noise. In locations with very strong mobile signals, verify that the LTE filter effectively reduces interference; if necessary, combine with additional inline filtering or a mast-mounted preamplifier designed for DVB‑T use.
