Who in their right mind would attempt a 34dbi increase?An increase of this magnitude is not a wise increase considering that an increase of 10dbi is a signal gain of 1000 times of all the ambiants (including noise).
An increase of 1-3dbi should make a difference and it might need a decrease rather than an increase, I'm talking about performance tuning, not going nuts with an increase so strong that the noise level becomes so overwhelming that there is no way the signal would not be drowned out.
