[sarex] Re: Possible ISS simplex operation, m

[MM]

Antenna:
Near as i recall.

FGB, Mono band, 2 co-phased antennas tuned for 147.xxx

Service module:

Antennas WA1, WA2, WA3 are all the same.
Multiband 2 meter, 435-438, Patch wide band 1.2-2.4
ghz.
Atenna WA4 is a 10 meter antenna ( do not have exact
length) and patch 1.2 - 2.4 ghz.
Each WA Antenna is mounted outside of the Service
Module onto a Hand rail.  The antennas are approx 90
degrees apart going around the hull of the SM.  The
Kenwood D700 antenna (WA1?) is mounted on the Earth
facing side of the space station.

I guess i need to update my web page with better
pictures of the mounted antennas.  thanks.
