There is a major difference between the two subjects.
If you did not master the skills of building a fire in wet conditions, you wont have a fire and have to eat the rat raw. Maybe you wont even have the rat to roast if you did not master trapping one.
A J-pole antenna can be build for a few bucks from simple materials and all the skill you need is soldering. It may lack some gain but itīs still going to work. I built one in less than 30 minutes. It allowed me to get connections at about 60 miles with good rapports. The antenna and the feeding cable roll up to a nice package that fit into my pants pocket.
If you are interested go ahead and try. You can improve later.
