Only one flight with this antenna. It does take some getting used to as it is more directional than the standard antennas. It does add some weight to the controller so using a neck strap helps a lot. Being the first flight I did not want to push it out to far but 1.38 miles is nothing to sneeze at 
If you get one and do the install you really need to be careful of small wires and do not over tighten the screws. Watching the install video a few times is a must.
