Which DVB-T2 / HEVC decoder to choose and can I connect it to the antenna withou

I have an old TV set and due to the imminent introduction of the new DVB-T2 / HEVC standard, I will have to buy a set-top box. I have two questions:

1. The TV set is connected only to an ordinary room antenna, will there be no problem with connecting the DVB-T2 / HEVC decoder to such an antenna?

2. Can you recommend any specific, inexpensive DVB-T2 / HEVC set-top boxes in the range of PLN 100 - 120?

ad.1. There will be no problem. For the dvb-t2 decoder it doesn't matter what antenna you connect to it. It is important that she receives the signal well
ad.2. There are many such set-top boxes on the market. You can often get the impression that it is the same decoder with different names and in a slightly different housing. There is a channel on YT with a lot of tests of currently available set-top boxes. Most often, their price is around PLN 100. Maybe you can choose something for yourself - https://www.youtube.com/c/TabletradarSmartTest/videos

I recommend Wiwa H.265 Lite. I had it and it worked fine.

I recommend the LTC tuner, good head sensitivity.
