[TowerTalk] High Power / Low Power ? / better antenna

[Gary Schafer]

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.
