The Iskra P2845 7F is a log-periodic UHF antenna designed for outdoor or wall-mast mounting. It covers channels 21–48 in the 470–694 MHz band and delivers 12.5 dB gain with a front-to-back ratio of 27 dB. The F-female connector version allows tool-free installation without a separate connector adapter.

The antenna supports both horizontal and vertical polarisation. Its mechanical redesign enhances gain and provides 4G/5G noise rejection, making it suited to areas with strong LTE or NR interference. An optional embeddable electronic filter (active or passive) can be added for further gain improvement or sharper 700/800 MHz noise suppression.
