The Iskra P2845-7 is a UHF log-periodic antenna covering the 470–694 MHz band (channels 21–48), offering 12.5 dB gain and a 27 dB front-to-back ratio. Its mechanical redesign provides enhanced gain and built-in 4G/5G noise protection without requiring an active filter. High-quality materials ensure long-term outdoor mechanical resistance.

The P2845-7 is available in four variants: with or without F-connector, and in horizontal-only or horizontal/vertical polarisation versions. This base variant (P2845-7) has no connector and is intended for horizontal polarisation only. It mounts on mast diameters of 20–50 mm in either horizontal or vertical orientation depending on the variant chosen.

Key Features

• 28-element log-periodic UHF design covering 470–694 MHz (channels 21–48)
• 12.5 dB gain with 27 dB front-to-back ratio
• Mechanical redesign for enhanced gain and 4G/5G noise rejection
• Horizontal polarisation; H/V version also available
• Mast diameter compatibility: 20–50 mm
• Antenna length: 118 cm

Product Benefits

• The 27 dB front-to-back ratio suppresses interference from behind the antenna, improving signal clarity in crowded reception environments
• Built-in 4G/5G noise protection reduces interference from mobile network towers without requiring a separate filter
• High-quality materials provide durable mechanical resistance for long outdoor service life
• Compact packaging dimensions reduce transport and storage costs for installers
• Four model variants (with/without F-connector, H or H/V polarisation) let installers choose the exact configuration needed
