Dehydrated broth

I’m wondering if anyone dehydrates their broth? I’ve seen some folks on YouTube do it but not sure how practical it would really be? I would like to make some dehydrated meals for my husbands hunting trips, and broth would be really helpful. I found a company that sells powdered dehydrated broth (beef or chicken) with nothing added. So I’m weighing the cost benefit of doing it myself. Seems like it could be very time consuming to get any reasonable quantity doing it yourself. If you’ve done it I’d like to know your experience.
Here is the site where I’m considering buying it

Since broth is mostly water, as you say it would take a long time to evaporate all that away, even if you put as little water in as possible. Vegetables and dried meat are both much more easy - I can imagine putting a broth mix together with those. I'd be inclined to buy a goof quality stock cube as Anne has suggested. However I did find a useful video on  this thread about dried stew mixes, suggesting using a slow cooker to give a dehydrated broth base:
