Description
The Iskra P20F DTT/G is a compact 20-element UHF aluminium antenna with an integrated DIGI-LOG 14VU amplifier. The amplifier boosts the received signal by 16 dB, raising the effective gain of the antenna-plus-amplifier system to 22.5 dB, making it suitable for locations where passive antennas deliver marginal signal levels.
Power for the built-in amplifier is supplied through the same coaxial cable as the reception signal — either from an external power supply or directly from a DVB-T receiver that supports antenna power. The amplifier requires power to operate; the antenna does not receive signals in passive mode.
Key Features
- 20-element UHF logarithmic aluminium antenna, 440 mm length
- Full UHF coverage: CH 21–69, 470–862 MHz
- Built-in DIGI-LOG 14VU amplifier with 16 dB amplification
- Combined antenna gain: 22.5 dB
- Amplifier noise figure: 2 dB
- Power supplied through the coaxial cable at 5–24 VDC, 25 mA (optional external supply or via DVB-T receiver)
- Integrated F female connector
Product Benefits
- 22.5 dB total gain substantially improves reception in weak-signal locations where a passive antenna alone is insufficient
- Power-over-coax supply eliminates the need to run a separate power cable to the antenna location
- 2 dB noise figure on the amplifier keeps added noise low, preserving signal quality rather than simply amplifying noise along with the signal
- Front-to-back ratio of 20–30 dB reduces interference from signals arriving behind the antenna
- Aluminium construction keeps the unit lightweight at 440 mm length, simplifying outdoor mounting

Why You'll Love It
- A single compact unit combines antenna and amplifier, reducing the number of components installed outdoors
- Power delivered through the coaxial cable means no separate mains connection at the antenna position
- Compatible with external power supplies or DVB-T receivers that deliver power over the antenna cable
- 22.5 dB combined gain opens up reception in fringe areas that standard passive outdoor antennas cannot serve
