Well, I remember in my pre-ham days on UHF CB (477 MHz) I was able to 
easily access a repeater 45km away using 5W into a length of feedline 
just sitting on a tin roof.  The path was fairly good, though not optimal LOS.

And after I got my ticket, I worked the local 2m repeater (5km path) 
using 3W into a dummy load on a HT (no feedline at all, it fitted 
directly on top).  Actually worked a station that way, just to say 
"been there, done that" :)

And with about 1' of feedline, 0.5W was rock solid.  As a matter of 
fact, when I had a fault in the mobile antenna, I didn't notice for a 
couple of weeks, because I was full quieting in from anywhere within 
30km, even though the feedline had become disconnected at the antenna 
base.  It was only when I went into town, further from the repeater, 
that I noticed something was amiss.

So, disconnected antenna from space being received on the ground?  If 
you ask me, quite possible!
