Description

The Kroks TV-20 Home is an active indoor television antenna produced by KROKS PLUS LLC, a Russian scientific and manufacturing company specialising in RF and wireless communication equipment. The unit integrates a built-in low-noise amplifier that delivers 20 dBi of gain across the entire UHF broadcast band from 470 to 862 MHz, covering every DVB-T and DVB-T2 channel allocation used in Russia's digital terrestrial television rollout as well as legacy analogue broadcasts in the UHF/ДМВ range.

This combination makes it a genuinely universal antenna rather than a single-standard device. According to the manufacturer, the antenna can provide reliable reception at distances up to 30 km from a transmitter or repeater, making it well suited for country houses, dachas, and locations with demanding terrain.

The amplifier draws its 5 V supply directly over the coaxial antenna cable from a connected DVB-T2 receiver or compatible television — no external power adaptor is needed in the majority of setups. A 75-ohm impedance and a standard TV-male (PAL) connector plug directly into any tuner without adapters.

The antenna measures 248 × 155 × 8 mm and weighs just 100 g, and can be fixed to a wall, window frame, or any flat interior surface. Kroks sells and supports the product through its own retail network.

Details & Equipment

Product Overview

Front view

The Kroks TV-20 Home in its flat panel form factor — the slim 8 mm profile keeps the antenna unobtrusive whether placed on a windowsill or wall-mounted indoors.

Antenna panel

The omnidirectional panel element spans 248 × 155 mm and covers the full 470–862 MHz UHF TV band without requiring directional alignment.

Connector detail

A standard TV-male (PAL) coaxial connector terminated at 75 ohms plugs directly into any DVB-T2 set-top box or television tuner input.

Mounting & Connection

Mounting hardware

The included mounting kit allows the antenna to be fixed to a wall, window frame, or other flat interior surface quickly and without specialist tools.

Installed position

Typical indoor installation showing the antenna positioned to maximise line of sight to the transmitter; the 100 g unit can be easily repositioned as needed.

Features

📡

20 dBi Active Gain

An integrated amplifier boosts received signal by 20 dBi across the full 470–862 MHz UHF band, enabling reception up to 30 km from the transmitter.

📺

DVB-T/T2 + Analogue

Supports DVB-T and DVB-T2 digital terrestrial standards as well as analogue UHF broadcasts, making it compatible with any TV tuner or set-top box in use today.

🔌

Cable-Powered Amplifier

The 5 V amplifier draws power over the antenna cable from the connected DVB-T2 receiver or TV, eliminating the need for a separate mains adaptor in most installations.

📐

Compact Flat Profile

At 248 × 155 × 8 mm and 100 g, the antenna lies nearly flush against any surface and is unobtrusive even when mounted on a window or interior wall.

🔩

Wall & Window Mounting

Designed for flexible indoor placement — the antenna mounts on walls, window frames, or similar surfaces using the included hardware.

🌀

Omnidirectional Pattern

The omnidirectional radiation pattern with linear polarisation and a 75-ohm impedance means no beam alignment is required after mounting.

Applications

Apartments and urban dwellings within approximately 30 km of a UHF digital TV transmitter Country houses and dachas where running a cable to an outdoor roof antenna is impractical Locations with challenging terrain — hills, forests, or valleys — that attenuate the signal reaching a simple passive antenna DVB-T2 reception via standalone set-top boxes or built-in TV tuners Legacy analogue UHF/ДМВ reception as a supplementary or transitional solution alongside digital services Temporary and portable setups such as hotel rooms, campers, or seasonal residences Small offices and meeting rooms that need background TV reception without outdoor equipment Replacement for a failed or weak passive antenna where amplified reception solves the problem without external cabling changes
