An UnUn is an *Un*balanced to *Un*balanced converter - The most popular 
types are those with a 9:1 winding ratio 
<http://www.hamgoodies.co.uk/unun-100w>.  We also stock a Multi-UnUn 
<http://www.hamgoodies.co.uk/multi-unun-250w> that offers 4:1, 9:1 and 
16:1 ratios.  This new product features a 1:1 ratio and is perfect for 
connecting SO239 unbalanced coaxial connections together.

Previously, Baluns+UnUns required a large toroid to handle high power 
and the varying matches across the HF spectrum - Our unique */No-Toroid/ 
solution* not only removes the need for a lossy core, but works from Top 
Band right up to 70cm.  It's also rated 1000-watts continuous thanks to 
its PTFE insulation.

  * 1:1 Unbalanced to Unbalanced convertor
  * 1000-watt rating - no lossy toroids!
  * Less than 0.025dB loss
  * Usable 160m to 70cm
  * Weighs just 35g
  * SO239 connections

_*Update : This was, of course, our /April Fool/ for 2017 but the above 
description was entirely accurate - Thanks if you shared this on the 
various social-media and news outlets :)*_
