Based on the search results, some of the best indoor TV antennas for reception in South Africa would be the Skyworth Compact Passive DVB-T2 Digital Indoor TV Antenna or the Funke Active DVBT2 Indoor Digital TV Antenna. The Skyworth antenna is compact, passive (no power required), supports DVB-T2, and offers a good balance of price and performance for R249. The Funke is an active antenna, so it has an integrated amplifier that could provide better reception in weaker signal areas, and it also supports DVB-T2 for R399. Both antennas have positive reviews and should be good options for receiving free-to-air channels inside South African homes without needing an outdoor antenna or signal from a satellite dish. Let me know if you need any other recommendations!
