This page describe the plan to build a new antenna array to mount back on the mast on the West Building (outside the Stag's Head). This would be of benefit to SUWS as well as other societies listed below.
Current Status
- Currently in purchasing and refurbishment stage as well as final planning on assembly and connections
Interested Parties
- SUWS (us) - General Amateur Radio operation / tracking high altitude balloons.
- Space Flight Society
- Interested in helping us.
- Interested in tracking satellite / high altitude balloons
- SUSUtv
- Interested in directional Wi-Fi for live campus broadcast
- Surge
- Interested in properly fixing their FM antenna
- Astronomy
- Interested in 1GHz-2GHz (?) radio astronomy.
- ECS Sensor Network Research
- 868Mhz omni for sensor network node
- There is still room for other interest should there be any
Antenna/Feature Ideas
Confirmed
- HF beam dipole
- triband 2m/70cm/6m omni
- 70cm+2m on dual-axis rotator
- SURGE FM broadcast antenna
- SOWN Wi-Fi @ coordinates
