[TowerTalk] Balun query

[Clint Talmadge]

If you have (or can borrow) an MFJ-259 there is an easy way to check. Short the output connections and measure the SWR.  1:1 means a 1 to 1 balun, 4:1 means a 4 to 1 balun. Even an old MFJ-249 will be sufficient to tell the difference.

  Fellow TTers:
  I have a bunch of W2AU baluns, none of which are marked in any way
  except the call sign.  I also have a Ultra-Bal 2000 model UB-1 balun.

  1.  Is there any way to tell whether a balun is a 1:1 or 4:1 or 
  whaterver:1?  

  2.  I have googled the Ultra-Bal trying to find its specs to no avail.
  Anyone know what kind it is?

  No, I do not own a network analyzer or have access to one.

  Thanks for any assistance.
  73,
  Barry - W1HFN
