I'm just looking for an antenna to receive airplane comms from about 20km with a semi-direct LOS, Just a couple trees in the way. I made a dipole antenna for this but have had limited success. Any ideas on directional 120mhz antennas or maybe how to make a yagi one?

I bought an entire radio at a garage sale that i can listen to airplanes on, only works for about 30km each way and cant transmit, but its pretty cool.

Let me know if you need help interpreting spec on anything.  I do RF engineering for a living.
