Are you a licensed amateur radio (ham) operator? You don't mention
a callsign, and some of your questions seem quite basic regarding
VHF & higher propagation, which suggests perhaps you are not.
Amateur radio in Canada and elsewhere has content restrictions and
is for non-commercial usage, which are not agreeable to most people's
general Internet usage. So for general wireless Internet access,
I suspect that the amateur radio solution is not the best general
solution.
I would suggest looking into license-free/exempt "WiFi" or 802.11(b)
wireless ethernet. These are low cost (cheaper than a commercial TNC
in most cases) devices provide low power (often 100mW) 2.4 GHz
(microwave) with speeds up to 11Mbps (802.11b) or higher (802.11g).
With a clear line of sight, and a small directional antenna
you can easily get a stable connection over 10km or more.
I would not recommend consumer oriented 802.11b for a Wireless ISP
(WISP) as they tend to have serious issues scaling, and the
license-free status means you must tolerate intereference.
