Humbug.
Go for the antenna as proposed in the build manual. That is a half wave
dipole, correctly polarized, and there is just nothing that can beat a
vertical half wave antenna in an aircraft. No antenna can give you more
gain, except when compromising the radiation pattern thus sacrificing
some coverage, which might be fine for a stationary antenna, but not for
an aircraft.
As for connecting multiple devices to one antenna: don't do it. You will
create ground loops, difficult to troubleshoot interference, etc.
