You are right: FloripaSat 1 is 44885.

Ron,
Commands were sent yesterday to re-enable the repeater, with no results.
It's likely the batteries have deteriorated far enough the transmitter will
not work. We'll keep trying for a while before any sort of announcement, but
to be honest, the satellite has been on borrowed time for a while. Please
keep listening to signals and telemetry for the time being.

I'm trying to understand, under what circumstances is a non-conductive
mast necessary at VHF/UHF frequencies. Thinking of the following installs.
1.? Circular polarized antenna mounted to the mast at the center of the
boom.??? This is clear, see this advice all the time, fiberglass mast.
2. Same antenna but mounted at the rear end of the boom.
3.? Vertical Yagi, elements parallel to a vertical mast, mounted at the
center of the boom. I guess, non-conductive wold be required here.
4.? Same antenna but rear mounted.
5.? Horizontal Yagi, elements perpendicular to a vertical mast, mounted
at the center of the boom.? I think this is pretty normal install, so a
conductive mast would be okay?
6. Same antenna but mounted at the rear of the boom.

The short answer is almost never. Here is a link to an AMSAT Symposium paper
form antenna guru Kent Britain, wa5vjb (inventor of the famous cheap yagis).
He actually measured the effects.

In addition, a general rule is that anything behind the reflector
element doesn't exist from the antenna's perspective. You can use this
to remove all the ground effects when adjusting an antenna for SWR, etc.
by aiming it straight up.

Oh, thanks guys. This is eye-opening.? It looks like even circular
polarized antennas will work with metal masts, if you rotate them 45
degrees.

I'm sorry - that's way too general of an answer to be accurate. Physics
says it's impossible to stick a significant piece of metal in the near
field of an antenna and NOT have an effect! The only valid question is
HOW MUCH OF AN EFFECT THERE WILL BE!

Cathryn,
And if you pay attention to all of the caveats in his paper. One saving
grace about all of this is it is not EME. If you were working with
250 +/- dB path loss and a passive reflector like the moon you might come
to a different conclusion. Just be careful of all of the those 1/2
wavelengths and 1 wavelengths that he speaks about. Especially for the 70
cm uplinks as that isn't very many inches.
The other thing I have seen folks trip over is coax selection. Satellites
are not the place to be using RG-8X. Others may have other thoughts I
think you are looking at LMR400 or its equivalent or better if it is a
permanent installation.

It's no worse than SSB as long as the power is kept down. Don't try it on
AO-7 though, please. About 10 years ago it was commonly heard on transponder
