I noticed, while listening in using either antenna, a noticeable amount of deep fades on the bird. I'm not sure if it was caused by
reflections nearby, or uplink fades on 1269 mhz.
If your fades are on the S band downlink it is you downlink antenna who probably gives you the fades. I tested a standard BBQ grill screen
meshed and i also got theses huges fades. When i switched to a linear 42 stacked elements (A WIFI antenna) theses fades disappear
completely. as AO-51 S band antenna is linear i guess a linear antenna is the best choice?
