Some time ago I bought a LilyGo module tuned at 433 MHz, but with the built in antenna I couldn't reach anyone. Is this to be expected? Can I put the module to some use?

No, you’re not! I’ve bought a second 433 node to find out if the problem was my node. Also, 433 MHz might work at higher frequencies
