Typical for WRT54G is about 35mw.
4 element collinear should have about 8dBi gain.

Impressive and much more than I would expect. The catch is that
although methinks you were able to see the WRT54G with Netstumbler, I
can't tell if you would actually be able to use the connection at
1400ft. My guess is that it would appear and disappear along with
reflections and interference.

That's Netstumbler. It never displayes WPA.

You don't want the RP-TNC on the end of a stiff piece of LMR-400. Use
N connectors on the LMR-400 and an N to RP-TNC pigtail, with more
flexible coax cable. However, if you insist:

Incidentally, the loss at 2.4Ghz for 60ft of LMR-400 is 4dB. That's
more than half your power and sensitivity gone in the coax (plus about
0.5dB per connector pair, plus pigtail, etc). You might wanna
consider doing PoE (power over ethernet) to the antenna, mounting the
radio on the tower top, and not using coax.
Hmmmm.... 16 element collinear should be about 14dBi gain (depending
on combiner/splitter configuration). Two of them will give you
perhaps 17dBi. Why not just buy a common 24dBi barbeque grill dish
and be done with it?
