Guys,
I've got some of these adapters and they are cheap. The wire breaks very easy.

What brand do you guys use that has decent sized wires so they don't break so easy.

Thanks.

What do yours look like?

Channel Master, outdoor ones. I'll get a part number when I get to the basement next (still recovering from a horrendous surgery). Lowest loss balun I've found to date with incredibly thick leads.

I have a RadioShack one kicking around that seems decent. Ben, hope you get well soon.

We used Channel Master 7282 or 8283's with the UHF leads clipped off - the 300 ohm lead was about 8 inches long, and we used the GC clothespin clips for connecting to the TV VHF/UHF terminals.

94444 is the outdoor balun - and they work extremely well.

I dunno if the 8283 is still made - seems it would've been obsolete in the 90s...

7982's are CRAP.

At the risk of a thread hijack, ditto on the wellness wishes. :thmbsp:

94444! That's it. All I'll buy for baluns, seriously. Lowest insertion loss at any frequency in the VHF range and they are virtually indestructible.

The leads on the average balun should not break unless you are swapping it around regularly....If you are* those 'GC clothespin clips' which are designed to be a quick connect between set terminals and ant/balun twin-lead are a good choice to substantially reduce strain on the wire. I think I still have a couple of spare clothespins floating around if you need them.

*I'd imagine they are breaking at the spade connector, am I right?

Right. At the spade connector.

Looks like the ChannelMaster 94444 is the way to go. My local Home Depot has them for $3 a piece.
Thanks.

I have a box of the 94444s around here. Each restored set gets a new balun and then I drag the coax to it. Way easier than fiddling with baluns each time I move a set, restore another one, etc

Right. That's why I'm looking for some!
