I believe it's mathematically possible, but in practice odds are good that there's something your height in the orbital path before it gets to you.
Reminds me a bit of the (mostly joking) concerns about the 51,000-foot mountain on the backside of the Moon when the lunar module was in a 50,000-foot orbit.
Everything I need to know I learned through Googling.
