how close is "live by the ocean?" I assume within a few miles (in other words Seattle does not qualify)

2. I don't see any beamwidth numbers for the C4 or C4V on the website but that thing can be a real potpourri of old and new stuff. Link where you saw it?

From the overview:
"...The ClearStream™ 4V has a 70+ mile range and a generous beam width of 70 degrees..."
I thought this was a little suspicious, as the Clearstream 4 has no such description, and should be the same (other than the included VHF dipole). Also, there is this:

...although I do have calculated polar plots and a gain vs frequency chart somewhere on my computer at work. I'll see if I can dig them up...

That would be interesting, thank you for the offer, but I'm not sure I really need them as your answer about beam width will suffice. Also, my particular set-up needs the beam width of the C2 (70 degrees) but I won't get into that (I've posted in the Help With Reception forum about my particular needs).
What I would be curious about however is how exactly do you define 70 degrees? or 60 degrees? Is there some industry standard, or do you choose an "arbitrary" dBi cutoff to define this?
Thank you!
