PSAS/ CommTeamTemp

Communication Team Workshop

Don't know when, but we should do one more test at the PSU Microwave lab with the VNA, hopefully before the 12/9 test at NW EMC.

Pre-lab:

  1. Timr adds a pass-through to the bell jar base plate (done)
  2. Tim makes a flat Teflon-dielectric CPA
  3. Glenn makes final balun for slot

Need to bring/have:

  1. Bell jar, base, CPA's, Vacuum pump, power strip, hoses, avionics module - Andrew
  2. Patch cords, automotive vacuum gauge - Timr
  3. Teflon gluing process? teflon-dielectric flat CPA? - Tim
  4. All reference dipoles and new slot balun - Glenn

The test plan:

  1. Suck tests

    1. Test Wifi CPA in bell jar at room pressure.
    2. Suck on Wifi: as many points as possible, at least 0, 35,000ft, vacuum. Then go down to look for hysteresis. How fast does the foam expand and contract? How long until it stabilizes?
    3. Suck on GPS as above.
    4. Suck on ATV as above.

  2. Slot antennas

    1. SWR/f0 on WiFi slot
    2. SWR/f0 on GPS slot
    3. SWR/f0 on ATV slot

  3. Dipoles

    1. SWR/f0 on WiFi dipole
    2. SWR/f0 on ATV dipole

If there's time left:

  1. f0/SWR on Teflon CPA.
