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
- We have some parts but we need but quite a lot of stuff needs to be bought, built or fixed (see Kit below).
- We need to have proper discussion with other interested parties.
- We need to come up with a final design of what will go on the antenna array and how it will be organised.
- We need to at least seek provisional permission for the antenna array to be erected ,so we are aware of any additional things we need to consider.
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.
- Tyler is aware of other interested parties.
Ideas
Sensible
- 23cm at bottom
- SURGE FM broadcast above 23cm antenna (we'd help them get back on the air)
- HF antenna of some sort
- 70cm+2m with dual-band rotator
- triband 2m/70cm/other vertical antenna on top of dual-band rotator
- Ask SUSU TV if they're interested (short-range camera links)
- SOWN Wi-Fi by coordinates
Varying degrees of silliness
- Pi camera
Plan
From top of the mast to bottom.
- 6m/2m/70cm collinear (AR+satellites+HABs)
- Spur bar
- FM Broadcast antenna (SURGE)
- 2.4GHz omni (sensor networks)
- 868 MHz omni (sensor networks)
- Elevation rotator
- 2m Crossed Yagi (AR+satellites)
- 70cm Crossed Yagi (AR+satellites+HABs)
- 5GHz Wifi Dish (SOWN+SUSUTV)
- HF Dipole (AR)
- Azimuth Rotator
Kit
Approved
- 2m crossed yagi
