I like little interesting data sets like this - they're wonderfull to look at.

These ones cover the off-baseline frequency of Odyssey during a UHF pass ( from a baseline of 400Mhz ) - and if data is good or not (0 - good data..no, I dont know why either)

They were used to help locate the rovers early on - but I think they also show a good profile of what a UHF pass is typically like. You can see the data drop out twice, one presumes as the Pancam Mast, and the LGA obstructed the line of sight from UHF mast to Odyssey - and again right towards the end briefly, perhaps because of HGA.

Interesting little graph anyway.

What about is that the UHF antena should be sitting on the top of Pancam Mast for MarExo since its small UHF stick is on the top base of rover. That is to avoid the drop signal due to the obstruction of near objects.

Well, perhaps another reason, if the Pancam mast doesn't deploy then you've lost your UHF too.. I suspect the main reason is simply space - not enough space within the enclosure for the UHF to not have to be retractable/foldable, with all the resulting complications considering the top of the mast rotates in elevation *and* the mast has to be hollow for the TES light path.
