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

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
868 sensor net antenna on spur

Sensible

23cm on spur
radio telescope (astrosoc)
monitoring node (temp/wind ect)

Current 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)
  - 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)
