Exactly. I can't build an amplifier from scratch or write microcontroller code but I'm pretty good at putting metal together in creative ways, so I'm always playing around with one sort of antenna or another. First, it was J-poles (2m, 220 MHz, 6m), more recently it's been playing with different Moxon designs (10, 15 and 20m) but I'm going to move on to Yagi-Udas and LPDAs next.
