Default More Long Wire Questions

What impedance would an end-feed infinitely long wire in free space have?
I'm about to put up 60 ft of wire 30 ft above the ground, and pipe it into
my living room. At first I intended it for 'DC to Light' receive only with
my new IC-R3 toy. But now I'm wondering if I could transmit into it on 2M
and 440. (I know this sounds chincy, but it's bound to get out better than a
rubber duck.) I figure at VHF and UHF 60 ft of wire would look like a
beverage antenna, except this wire is going to be many, many wavelengths
above the ground. So what does a wire many, many wavelengths long, many,
many wavelengths high look like? Would I need a balun?

What would be a good reference be for questions like this? The books I have
here and Google never seem to have the info I'm looking for.
