Outdoor antenna Iskra UHF channel 21–48 (470–694 MHz)

Iskra outdoor UHF antenna for channels 21–48 (470–694 MHz) is designed to receive terrestrial digital television signals across the UHF band. Constructed for external mounting on roofs or masts, the antenna provides stable reception of DVB-T/T2 broadcasts within the specified frequency range and is intended for household, cottage or shared-installation use where UHF coverage is required.

Advantages

The antenna offers broad UHF band coverage from 470 to 694 MHz, ensuring compatibility with channels 21–48. Its outdoor design and mounting options on roofs or masts improve line-of-sight reception and reduce indoor signal losses. The device is engineered for stable performance in typical domestic and rural environments and maintains consistent reception for digital terrestrial television standards used in many regions. Durable materials and a compact form factor simplify installation and long-term outdoor exposure.

Suitable for

• Receiving DVB-T/T2 terrestrial broadcasts in the UHF range (channels 21–48)
• Installation on residential roofs and masts for home or cottage TV reception
• Communal or multi-dwelling setups where an external UHF antenna feeds multiple receivers
• Locations with moderate to good line-of-sight to broadcast towers where external antennas are preferred

Key specifications

• Frequency range: 470–694 MHz (UHF, channels 21–48)
• Application: terrestrial digital TV reception (DVB-T/T2)
• Mounting: roof or mast installation compatible
• Operating environment: outdoor use with weather-resistant construction
• Polarization: designed for standard horizontal/vertical UHF broadcast polarization (check local broadcast polarization if necessary)

How to use

Mount the antenna on a suitable roof bracket or mast at a height that provides the best line-of-sight to the local broadcast transmitters. Run coaxial cable from the antenna to the TV or set-top box, using a quality outdoor-rated coaxial cable and appropriate weatherproof connectors. If the installation will feed multiple receivers, connect the antenna to a distribution amplifier or splitter rated for UHF frequencies. After connection, scan for channels on the TV or tuner to tune DVB-T/T2 services within the 470–694 MHz band.

Usage recommendations

Place the antenna as high as practical and orient it toward the nearest broadcast tower for optimal reception. Use high-quality outdoor coaxial cable and waterproof all external connectors to minimize signal loss. If signal strength is weak, consider adding a low-noise amplifier or checking for obstructions between the antenna and transmitters.
