Hello Jenny,
Congrats and Great idea, and very light and useful, and most of all it is always full lenght for the band you want.
Do you know this antenna can be built for 2 or 3 bands with 2 or 3 reels on each side ?
Look at the link here:

Normally those plastic reels are use with a simple rope for a clothes line during camping trip.
So you replace the rope by some lightweight wire and with a couple of isolators, you are in business.
Good dx'ing, & Have fun everyday
