Hi!
I will drive to eastern Arizona for the afternoon/early evening
of Saturday, 8 August 2009, and plan to work FM satellite passes
from the DM54/DM55 grid boundary in Apache County. I should be
able to work AO-27 passes at 2046 and 2227 UTC, an AO-51 pass at
0041 UTC, and an SO-50 pass at 0134
Advanced Receiver Research http://www.advancedreceiver.com/ and SSB Electronics
http://www.ssbusa.com/ both make excellent units.
I use SSB, and I'm very happy with them.

Hi, Mark,
The 902-928 MHz is not available for space stations in any radio
service. 2400 to 2450 MHz is available to the amateur-satellite
service. However, many of the example projects appear unrelated to
radio or may be commercial in nature, so they may not qualify for the

I have been using keepers and insulators that I found at my locally
owned hardware store. Don't go to the big box stores, they won't know
what you're talking about. I use an Ace store, because it's close to my
QTH, but any decent one with good selection of small parts should have
them.

Try a grounded radome to keep rain and air movements off the antenna.

don't forget the velocity factor too!
My first thought was to try to find out where the static is coming from
in the firstplace and fix that. Why put a band-aid on a cut when you
prevent the cut in the first place?

Hi Lars, OZ1BXM
The shorted quarter-wave coax line suggested in the ARRL Handbook 2008 and
2009 pages 23.20-21 will work great because it is a short circuit for the
static electricity and a theoretically infinite impedance at the resonant
frequency so that for the RF input signal it is completely

Michael,
Many years ago I purchased such parts from Texas Towers as I made some 2M yagis
for Meteor scatter.
These parts are not in the catalog but try asking by calling them. They also
sell aluminum tubing for making antennas.

Hi Michael,
Not sure if you got a reply, but for C3i try contacting Owen, K3CB.
I also thought at one point, M2 had the plastic insulators and stainless
keepers as they were doing some KLM stuff. I don't see anything in their
catalog, but might be worth a call.

Hi Lars.
Can I suggest:
1) A 47k resistor across the input of your converter. The static will have
a very high impedance and I've found 47k will remove it without increasing
the noise figure of your converter.
2) For really severe cases. An inductor to ground. An 0805 or smaller

You raise the question of licensing 'in-orbit' devices and the potential
