probably. I am only guessing but when they say "runs with the maximum 1-watt power output allowed by the Federal Communications Commission for 2.4-GHz equipment" I assume they don't mean 1W power out of the bridge, but rather 1W effective. So assuming 24Dbi antenna's (the highest gain parabolics I have seen for 2.4Ghz) the should be ok with 100mW bridge units which is probably what they are using. I did not see them mention amp's anywhere in the article.

Is there anyway to use seperate transmitting and recving antennas? You could use a big honking dish for the recving and a much smaller one for transmitting?

or perhaps they already had access to a tall building, or some cliffs, thus obviating the need for a large tower.
