The Iskra P-41-7 CF is a member of Iskra's TRIPLEX series of outdoor UHF antennas. Mechanically tuned to channels 21–48, it is designed specifically for the reception of digital terrestrial signals in DVB-T and HDTV formats, delivering gain of 11.5–16 dB across the UHF band.

With 41 elements and a tighter beam profile than comparable antennas — 32° horizontal, 35° vertical — the P-41-7 CF is suited for installations requiring a more focused directional pattern to reject interference and improve signal quality from a specific transmitter. The integrated F connector enables direct connection to standard coaxial cabling.

Key Features

• 41-element Triplex-series Yagi antenna mechanically tuned to CH 21–48
• Frequency range: 470–694 MHz (UHF band)
• Gain: 11.5–16 dB
• Front-to-back ratio: greater than 27 dB
