I have a 2m Slim Jim in the loft fed with about 12m of RG58 coax. This is far from ideal, but the cabling was put in when I first moved in for HF - I have three such cables that go out of the shack wall, up the front of the house and into the loft. It isn't too ugly, but RG213 would have been far uglier and I have the "station manager" to consider!
The Slim Jim combination usually gives an S2-3 signal on a 20-40 degree passes using an Icom IC-7400 with the pre amp on - it hit S4 this morning. I don't think this is ideal, but it gets you going and when the signal strength comes up it gives 75-100% packet decode success.
For two-way comms when the satellite is in shadow and running low power I think a beam is going to be much better. I have a two element Moxon for 2m that I can set up just outside the house with a short length of coax. I'll report back if it is better.
PS I note that the spacecraft is appearing a little later than the Keps I was using predict. I have just upgraded them to:
1 39417U 13066B 13328.52822701 .00004709 00000-0 65186-3 0 152
2 39417 97.7995 41.0710 0063010 185.6906 174.3718 14.77115537 473
and it seems a little more accurate. Where the Keps not quite right or are we seeing the effects of drag?
