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.


Hi Jimmie,

Have your tried researching the archives for this topic? *Google's
search tools can easily provide those answers.

What do you have that is
1. a 200 Ohm load, or
2. a 12.5 Ohm load?

Is it balanced, or unbalanced?

Does this BalUn have a pedigree (like Radio Shack's "Best TV") or
could it actually be an FM BalUn?

If it is a TV BalUn, which band?

How much power are you going to apply to the load?

Googling TV BalUn was useless but searching fot 2M Balun proved more
useful. Per an article by K3MT they should be able to handle power in
the 5 to 10 watt range. More than enough for my purpose. I cracked
open a couple and foundd that tthe type that go frm screw connectors
to male F connector have a larger transformer than the barrel type.
This was at least true for the couple that I sacrificed to the radio
gods.
K3MT"s data was on the barrrel or tubular type.
