Let me preface this with a simple disclaimer: I’m very much a newbie at Satellite projects. I’m by no means an expert. I have two simple concerns:
Where it the target customer base?
Are neighboring satellites going to interfere with the desired satellite signal?
- We really need to look at what is the best signal coverage for the target audience.
Here is a population density map for North America. Which satellite covers the target population better? You may have a better customer base sample in your sales records. I understand that in the future you want to provide coverage for areas that are in the fly-over parts of this map, but initially, you will need to be able to target the masses of experimenters that will try this system out and perhaps take their outernet device with them camping or on trips across the country, etc.
- The other factor in my mind is the beamwidth of a raw LNB or a smaller, lower gain antenna. With a larger dish antenna, we can focus in on one satellite. With the smaller, lower gain antenna, we will have to contend seeing more than just one satellite. I guess the best way I can illustrate this is with this photo of Christmas lights.
With a satellite dish, we may be able to see just one of the Christmas lights at once. With the smaller, dish, our field of view may include three of those bulbs. If the neighboring satellite on the target frequency has a transponder also on the same frequency with the same polarization there may be more interference than if the neighboring satellite is using the opposite polarization, etc.
Will we see 6 degrees wide instead of just two? Will this bother us?
So where are the neighboring satellites?

Maybe someone can chime in and tell me that I’m nuts, or help me understand better.
