The potential problem is
the long run of cable up the mast which will create a lot of signal
loss even with the very best LMR400 cable.

That cable has a loss of about 6 dB/100 ft at WiFi frequencies. A colinear
antenna can have gain way in excess of the loss and maintain an isotropic
pattern in the horizontal plane. Figure 50' of cable with 3 dB of loss added
to a 9 dB gain antenna is a net gain of 6 dB. It could work out quite well.
One has to consider the entire system, not just isolated elements. This is a
much cheaper and more reliable solution than an active bridge up on the mast
head.

Glory!
