Here is an example of an effective antenna built on a budget. It is a horizontally polarized 6 element beam for 222.1 Mhz single sideband. We are going to use it for our limited rover. Credit goes to WA5VJB for his “cheap yagi” (do that exact internet search) plans that made it easy to build. Just click and drool. Get thee to a hardware store and build your own beam on a budget.
