If you want an emergency hf antenna at practically no cost, then try this antenna idea from Simon (VA7BIX).
In this video, Simon shows how ordinary ethernet cable can be used to make a 5-band hf antenna with ground radials.
Make one of these antennas for your emergency "go-kit" or to keep at your home station.
Don't toss your old ethernet cables away--convert them to ham radio antennas!.
