You didn't say what band the repeater would operate in?
With 145 feet of cable I would assume that the antenna would be something
less than that in height above ground?
The higher gain antenna will give a little better performance on the receive
side of the repeater. But if this is going to be at VHF that size antenna
will be a handful on the tower.
