Jimmie,
I have tried and used these tv baluns so I could run 300-ohm cable to my
antenna. BUT I only ran about 5 watts.
I used one on both ends of a 100-ft run of 300-ohm cable ( so as to reduce
losses) . (And I used it on 10 meters, not 2 meters)
I later wound my own impedence-matching 4-to-1 baluns to handle a full
100 watts.
You're on the right track of having fun with transmission lines, impedence
matching, and antenna building - keep it up.

I was considering using a TV type 4:1 balun on 2 meters. Does anyone
know how much power these can handle? I remember a guy doing this when
I was a teenager(long ago) but I think the baluns were built a little
stouter back then than they are now.
