    Most of the gain you will get from the X50 is in the use of better coax, plus the height gain.
    Here's a height/horizon calculator, have a play to understand how antenna height affects your horizon.
    You might be able to find a (better) graphical version for your location to show a coverage map.

    You'll hear more signals on the same antenna using better coax because the signal from the antenna is not attenuating on it's way to the receiver, especially for VHF.
    Same goes for the transmitter, less signal is lost before it reaches the antenna to radiate, so you need less transmitter Watts to make the same signal level at the other end.
