The Iskra DTX22F is a YAGI-type UHF outdoor antenna with 22 elements and a metal reflector. It covers the full UHF band from channel 21 to 69 (470–862 MHz) and delivers 10–14 dB of gain across the band, with a front-to-back ratio exceeding 28 dB for strong directional performance.

The metal reflector improves front-to-back isolation compared to designs using a simple dipole element alone. An integrated F connector provides a direct coaxial cable connection without requiring additional adapters.

Product Benefits

• YAGI design with 22 elements achieves 10–14 dB gain, enabling reception of terrestrial signals from distant transmitters
• Metal reflector raises front-to-back ratio above 28 dB, providing strong rejection of interference from signals arriving behind the antenna
• Greater than 28 dB front-to-back ratio is particularly useful in urban environments where reflected signals can degrade picture quality
• Integrated F connector reduces the number of external connection points, lowering the risk of weather-related connection degradation
• 810 mm length positions the DTX22F between compact and long-range antenna classes, balancing size with performance
