Marshall - Your EME rover scenario is very tempting. I may give it a go.
I assume that you are using one of the WSJT modes?
What kind of EIRP is necessary for a rover to make a couple of EME
contacts during a contest on a rising and setting moon?
Let me cut to the chase, is EME possible from a typical rover running
say a Cushcraft 13B2 driven by the ubiquitous 150 Watt brick? Or a
pair of the 6 element WA5VJBs?
Or is that long Yagi you talk about longer than the car?
I love the WA5VJB cheap Yagis and have made lots of them. They have
good clean patterns and appear to have good gain for their length. So
with a 400 Watt Amp and the 4 - 6 element Yagis you have about 12kW
EIRP? I think that it is pretty straight forward to generate 3 kW EIRP
on two in a rover, but much more than that starts to complicate set up.
What is the optimum height of an antenna to maximize ground gain?
As you can see, this is intriguing to me. - Duffey
