The high frequencies make it far more difficult, way back down at 145MHz you adjust aerials by cutting off a few mm at a time - at 2.4GHz you would need to be trimming small fractions of a mm for the same effect.
This supposes you have the required test equipment to do so at these frequencies?.
I have another base station with an antenna that should be the right size. What cable should I run to the cellar to connect the antenna and how do I connect to the existing antenna up stairs and would the connection change the impedance of the system?
