[600MRG] Ground radials

[Brian, WA1ZMS]

1) My appologies for the banter

2) Andy would likely get a better measured evaluation of the effectiveness of any added counterpoise wire(s) by simply measuring the RF current in each wire. Kirchhoff's current law always applies.  

Example:
When building my T-ant 10yrs ago for XSH/31, it was very helpfull for me to measure the slight current changes in each wire added to determine just where RF was flowing.  It also helped show how effective adding ground rods at different points in the system really was.

The result of doing the measurments and carefully adding wires & ground rods (on my 0.6ac lot) resulted in a ground impedance of around 40 ohms on 2200m and around 20 ohms on 630m. Soil moisture still has an impact, but it's only a couple of ohms change on either band. I can live with that.

And yes Dave.... I am heating the soil with most of my RF. I know that. :-)

But this T-ant is also my 160m dipole. Given where my trees are located and the esthetics of the wires it was *my* best solution.

>> Don't you just love the English Language, especially that dialect used in the United States!  The same word, as spelled, can have a number of different meanings even within a single discipline.  If one does a "Google" on "termination" several different definitions come up and then if one does a "Google" on "electronic termination" even more definitions come up such as "a wire termination is the work performed to the end of a wire that allows it to connect to a device".

>> 
>> 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.
