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.

Facebook Group

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
  • 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)
  • HF Dipole (AR)
  • Azimuth Rotator

Tasks

Allocated

  • Create CAD diagram of mast and ALL parts
    • Tyler

Unallocated

  • Get permission from susu regarding rack for room and wall mounting
  • Check with E&F
    • lighting protection
    • wall mounting
    • planning
  • Calculate coax lengths
    • source coax connectors
  • Finish HF dipole refurbishment
    • Design new crossbeam
    • find missing parts

Coax Info

Information sourced from Coax Data and ML&S

Prices sourced from ML&S inc. VAT

Diameter RF Loss Max Power Handling Cost Datasheet
mm dB/100ft @ 400MHz W @ 50MHz (1:1 SWR) /25m Reel
RG-58 5 10.5 450W £20.70
RG-213 10.3 4.5 1500W £32.25 http://www.romkatel.ro/cataloage/pdf/eupen/RG213.pdf
Ultraflex 7 7.3 3.59 1820W £29.70 http://www.messi.it/dati/immagini/RGAC7PLUS-All1_EN.pdf

Note: Connectors for Ultraflex 7 are uncommon, and so may add significantly to the expense.


Lightning Precautions

  • Talk to E&F about:
    • Current mast situation
    • Building requirements
  • Can we rely on lightning path through the rotator body?
  • Kit will be toast whatever happens, priority is mitigating fire risk.


Static Protection

  • Resistive bleeders on all coax
