Features Specifications:Sell LK900 DVB-t & UHF Antenna  Ideal companion for traveling around the world or at home 5V power supply compatible with USB Slim and compact design LK900 is a compact antenna specially designed for the best reception of digital TV (DVB-T) signal and it is the perfect companion for a laptop tuner. As we studied market we found that 99% of notebook and USB tuners are coming with a tiny and almost useless antenna (you can use a piece of any wire with the same result). And this means that if your laptop or computer is in a location with strong and stable TV signal, everything is working fine but it can happen you travel to some rural area or you are in a commercial building with a lot of signal obstructing constructions around it so the transmition signal is very weak or reflecting - here our LK900 is the best solution as it has built-in amplifier (adjustable up to 30dB gain) with large reception area, slim and flat, and does not require a special power supply as you can use any USB port 5V/300mA to power it on and is easily fit in almost all carrying laptop cases and bags.
