I recently purchased an ICOM IC-A23 radio, and I'm disappointed in its
pickup. It gets the weather channels fine, but the reception for both the
airport and airplane radios is poor. Aside from standing next to the
airport or being right under the airplane, do I have any options for
improving gain and the quality of reception? Is there some third party
antenna that I could attach to this radio? It looks like it takes a
standard BNC type connector for the antenna that comes with it.

If you are on the ground, outside the airplane, you can purchase a
metal, 5/8 wave, telescoping antenna to replace the standard rubber
duckie.
