USB UHF DVB-T TX transmitter add the PA ( power amplifier) distanace about 500m

This is a DVB-T TX experiment. The more information is as below link http://febon.blogspot.com/2014/05/usb-dvb-t-tx-modulator-transmitter.html I let WINDOWS video clip become Wireless DVB-T and also add the Power amplifier (PA) I use the cheapest antenna. I do not do any optimize . The wireless distance in the video demo is about 300m ~0.5KM. The wireless distance can be up to 2km when you do the best optimize. Environment and tool: 1. USB DVB-T TX DONGLE ( WINDOWS only version) http://febon.blogspot.com/2013/10/windows-version-user-manual-for-usb.html 2. Power amplifier (PA) 3. The distance between antenna dongle and PA is about 300~500cm 4. The best location of antenna is open void (wide spacious) ( in my video demo, it is not 100% spacious and empty-void.)
