Crossed Yagi 144 MHz, 10 elements, switchable vertical and horizontal polarization
Helix 435 MHz, 7 coils, clockwise circular polarization
In particulary the crossed Yagi is made by Cush-Craft while the helix is a home-made, following the article published on VHF-Communication that is available HERE (1 MB about).
How my antenna system works?
Since my antenna system is devoted to satellite traffic, I need a "mast" that allows me rapid changes!
Really, during the antennas "testing" for traffic via satellite, the greater part of the time is spent to calibration of the relative accessories (preamplifiers, splitter, etc), while, normally the parts that reside in "shak", endure small modifications!
This consideration, addressed me towards a telescopic mast, but enslaved from a small whinch, because the antennas and the two rototors weight (azimut and elevation rotator), carries to an effort that would be also dangerous (... the fundamental condition to enjoy radio is to be alive after the installation!).
In this photo you see, a possible "home made" solution; there are commercial solutions truly attractive... but more expensive too!

In this photo indeed you see the rotators: about rotators is not possible to joke and "home made" solutions must be well evaluated. My rotators are commercial one and for this reasons, it is the part more expensive that I have!
Rotator DAIWA for azimut and KEMPRO KR 500 for elevation
