greetings everyone

please I bought 1 of this FTA digital terrestrial receiver (T26), so I connected my Startimes antenna to it and scanned for stations only for it to display about 200+ all locked showing scrambled and I also noticed that in the channels list, each program is having this $ in front of it.

please, if I connect a strong dish or local antenna to it, will I be able to watch our Nigerian local stations without having to pay for them
