Michael, please do not spend good money for something you can build
yourself for a fraction of the cost, and learn good things in the
process...
An 8X10 piece of plexiglass storm window from the hardware store will
supply strips for the end and center insulators... A chunk of 300 ohm
TV twin lead will supply the folded dipole material... A roll of coax,
some solder, and a pieces of small rope, and you are in business... A
hack saw will cut the plexi (so will a skill saw or table saw)...
Why not make one for 10 meters as a starter until spring comes... This
can be hung between two trees or whatever so it is at least head high
and will give you some fun when the band opens here and there..... You
can check the formula for length versus resonant frequency...
