I am extending my post a bit. I have done lots of reading to figure out what is the best setup and will share Some thoughts on the best antenna setup for the given frequencies of 144 mhz and 435 mhz. As previously mentioned for this specific case circular polarization is best. But you are still stuck with the antenna decision. The lower band will require a bigger antenna for sufficient gain and the SNR you will be really low.
Helical antenna for 435:
+Relatively easy to build
+Circular polarization
+Moderate size for 435 Mhz
-Not feasible for 145 MHz (would require about 1.3m base radial diameter)
(Cross)Yagi for 145 or 435 MHz
+can be build as dual band configuration
-quite big
-requires matching, mantle current filter
-cross yagi additionally requires lambda/4 phase shift harness. In practice you may loose a lot here.
Turnstile
-Not directed
-Gain is -3dB versus the dipole. OK for NOAA and ISS but surely not enough for cubes.
