Amateur Radio Microwave Gear and Projects
Find resources for building and operating microwave equipment across various GHz bands for amateur radio communication.
Operating on microwave bands, typically above 1 GHz, offers hams unique challenges and opportunities for experimentation. These frequencies allow for very narrow beamwidths with small antennas, making precise aiming crucial for successful QSOs. Operators often engage in line-of-sight contacts, tropospheric ducting, and even moonbounce (EME) on these bands, pushing the limits of amateur radio activity.
Many hams interested in microwave operation focus on homebrew equipment, building their own transceivers and amplifiers for bands like 10 GHz and 24 GHz. Projects often involve modifying commercial radio-relay gear or designing custom circuits, as seen with G3WDG and F4DAY equipment. This category provides practical resources for constructing and understanding microwave systems, from basic narrowband setups to more complex designs for higher frequencies like 134 GHz.
