Hi to all:
Does anyone have a copy of the W5DWT 73 Magazine article?  I think it may have been printed near 1963?

There has been an on-going discussion on this very forum about link tuners. One of the responders is Tom Rauch, W8JI. His comments about a properly designed T type tuner, and requisite balun will give you a concrete base to hang your hat on.

Every antenna tuner, no matter the configuration, has some drawback(s). For the most part, the T tuner, with a decent 1:1 balun, will equal, or out perform, any other tuner configuration. You might find some loads which are better served with a different configuration, but not many.

If you design a link tuner for a specific system, like a 135ft flat top fed with open wire line you can design a very efficient tuner.  If you goal is to match a wet noodle a T tuner may be a better choice.  It's all a trade off, efficiency vs range of loads matched.  Most people think a wide range of matching possibilities is most important but its only really important in the case where you are going to be trying out a bunch of different antennas.  Once you decide on a given antenna power transfer is most important

I've built link coupled tuners with band specific plug in coils for a given antenna, and I highly recommend it.  its much easier to plug in a coil than to spend half an hour goofing around with a roller inductor once you have your system characterized.

W9OY:
Thank you for your info.  

My first link coupler had plug-in coils too.  I agree, this is a very nice antenna coupler.

Anyone havae or know where I may find a copy of the 73 Magazine article by W5DWT on the link antenna coupler?  It may have been published in 1963.  I am not sure.
