To op...is your antenae powered?
Since you are in apt you may be limited in your options. Try getting one that is plugged in.
If you want to take a flyer...run a cable from cable jack on wall to tv ant in. Essentially use the coax wiring of entre bldg as your antennae.
what kind of sick weirdo are you? you watch NBA?
I have trouble pulling in 5 after they switched to Lo-V too. A few things you could try: make sure the cable you are running between the ears and your tv is the newest RG-6 type and solid copper if you can find it. Also the shorter the cable between the two, the better. I'd also probably get a powered indoor antenna. I live in Urbandale too and I think I can re-position my antenna and probably get 5 to come in better, just haven't done it yet.
This site will tell you what channels you should be able to get and what direction to point your VHF and UHF antennas.

I've got a big arse antenna on the roof of my house ala 1975. Works like a charm.
Yeah, channel 5 is hard to get because of the low frequency... You pretty much need a decent sized vhf antenna.
Ideally Channel 5 would switch to a higher channel, but you should be able to get it in with something like this: Winegard HD7015 VHF/UHF/FM Prostar 1000 TV Antenna (HD-7015) from Solid Signal
on the roof or in the attic.
Use this link to build your own from coat hangers. This works. I use this when tailgating. [ame=http://www.youtube.com/watch?v=EWQhlmJTMzw&feature=youtube_gdata_player]Coat Hanger HDTV Antenna! - YouTube[/ame]
