For $20, or so, you can get all the parts you need from Home Depot or Lowes to build a "copper cactus" J-Pole antenna for 2 meters.

For a heck of a lot less, you can build 1/4 ground planes for both 2 and 440 -- using an SO-239 connector and a coat hanger.

From what I've seen of the specs, this is a J-Pole made out of twin lead (they're available online, just search.. for example, http://www.rollanet.org/~rrars/tech_files/ select the '300 Ohm Twinlead dual band Jpole .PDF file). Nothing you can't do on your own.

But this antenna will only give you local V/UHF coverage. No HF. Certainly no DX.

I don't expect it will have much impact on the zombies, either.
