SUSU Antenna Array

This page describe the plan to build a new antenna array to mount back 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
• 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 levels of silliness

• Large SUWS flag on top concealing a loop antenna

Plan

From top of the mast to bottom.

• 6m/2m/70cm collinear (AR+satellites+HABs)

• FM Broadcast antenna (SURGE)
  • 2.4GHz omni (sensor networks)
  • 868 MHz omni (sensor networks)

• Elevation rotator
  • 2m Crossed Yagi (AR+satellites)
    • eg. 8-ele Tonna
  • 70cm Crossed Yagi (AR+satellites+HABs)
    • eg. 19-ele Tonna (probably too long)
  • 5GHz Wifi Dish (SOWN+SUSUTV)
    • eg. 802.11ac Ubiquiti PowerBeam

• HF Dipole (AR)

• Azimuth Rotator

Kit (Incomplete)

Have

• 2-axis Rotator
• Triband vertical
• Poles

Required

• More coax

Needs Building

• 2m Yagi
• 70cm Yagi
• Remote control computer

Needs Fixing

• HF antenna
