Thanks Glen. 
BUT after 50+ years in the antenna and communication industry,  Termination has several definitions depending on which group of engineers you are talking to ....So,  You are correct only in certain regiments of technology.  You ask a Broadcast or Microwave engineer, and you would be questioned as to what you meant.   For me, termination means something that is either a dummy load, dissipation line, or Ground.   
Your reference to a "termination at an antenna or dummy load" is confusing. The first is incorrect the second is correct.  Termination in it's simplest meaning is END, not a junction.  In a train ride, arriving at your destination is the termination of the trip. Going further it was a connection..... IMHO  end.

Termination, in "antenna talk", is NOT confined to connections to ground.  It is also definitely possible to have a "termination" of a feed line to the radiating portion of an antenna.  A "termination" is nothing more than a connection point.  Now, "termination" is often used to describe the last connection in an installation such as "the feed line terminates (has a termination) to a dummy load.

The term "termination" in antenna talk means either a connection to GROUND or and Connection to GROUND through a resistive element.  Like in a beverage the end is TERMINATED in a resistive element to ground.  In Andy's antenna he connected the radials with a circumference conductive line. No termination was made as he indicated no connection to ground........
