You may need to specify what kind of antennas you use?

if your antenna is beam antenna,then use the smith tool to do,if your antenna required to carry high power such as 1 kilometer,it is more thing to think about

sorry, 1KW

hi,
first of all you should know the impedence of your antenna... then you can design the matching system.

In many cases the antenna is a balanced device and the feed is not, don't forget the balun.
