Hello there! I'm not very good at lithuanian (I can understand it quite well, but can't write on it). Hope you gonna forgive me for that, that I'm writing on english.
I wanna watch your DVB-T television. Unfortunately, I don't have the needed information, so I can adjust my antena (aerial) and choose better and stronger transmitter. Maybe you can write here transmitted power (in kW) from these transmitters in your country:
Biržai
Visaginas
Viešintos
Rokiškis

In return for your help I can give to you information about our DVB-T in border area if you want. Transmitters, which carry FTA channels are turned on across all the country.

Ačiu!!

So, here are the FTA MUXes (transmitters) carrying 5 FTA channels:
LTV1, LTV7, TV3, LNT and TV5:
