Just picked up a radio that will easily fit into the pocket in my HH. It is at Walgreens and is made by Coby. It is an AM/FM with a digital display (analog tuning) , built in speaker, clock with alarm and earbuds. All this for $5.00. I sleep in the back yard quite a bit and this is really great. It is a little smaller than a pack of cigarettes.
When it goes over their heads, it really doesn't matter how high it is.
