Without any doubt, ANTENNA is the most important part in radio communication of any kind. I've dedicated a lot of time to design, improve and build over 250 Yagi antennas on all amateur bands between 14 - 432MHz. I occasionally built Yagi antennas for 27MHz (Citizen Band) and 88-108MHz (FM radio enthusiasts).
