A word about the difficulty avoiding accidental hijacking of the original posters thread.

It is hard to be tolerant, while tolerance is a lesson we all could benefit.

Some folks are more passionate than others.

Some are Teachers.

Professors

Doctors PHD science or Physics

The point is we gather together here from all walks of Life.

As Ham operators We all have a common interest in a specialised area of Science.

Antenna systems.

We are a small group of folks that can exchange ideas and truths and try to expell myths and we are joined together via the fraternity of Amateur Radio.

Lets try to remember that during our sometimes passionate exchanges.

You left out another factor: some of us are ADHD.

Hi it's my Elmer Bob. Methusalah  Grin

One might ask w5wss after 43 years as a ham you have an Elmer?

Yep.

Any links to a hijacked thread so we can see an example??
Apparently "Antennas and Towers and more" has had many problems.......dunno

Some people consider a thread highjacked if someone posts a comment about a comment someone else made that was slightly off topic.  That is why it's important to read the entire thread before such statements are made. 

Yes, we're all interested in antennas, but even in the subject of antennas, there are many different, well, sub-subjects, if you will.  Just because one commenter made a point about how an antenna functions doesn't mean that the thread is highjacked if someone else comments on how its mounted!   Grin

I agree with that. I seen many times where some one ask a question and another person starts to make a comment that really did not answer the original question. But the topic still related to the subject on hand. Personally i appreciate the extra input as it some times sheds light on the the original subject that may have been over looked or misunderstood.

Like this one? "On 80-meters, and actually over a fairly wide frequency range, (test coil) time delay is about 3nS. ... Without shunting capacitance throughout the length of the inductor, current would be equal at both ends and phase delay would be zero."

What should ideally be done with technically incorrect "pet agendas and favorites arguments" like that one?

Did I just hijack this thread or did I merely make a logical connection from Tom's above posting to his web page contents?

P.S. People have been complaining about thread drift (hijacking) as long as threads have existed. Such people apparently have never read Connections, by James Burke.

The purpose of an antenna tuner is to increase the current through the radiation resistance at the antenna to the maximum available magnitude resulting in a radiated power of I2(RRAD) from the antenna.

I guess you could call this thread "hijacked" http://www.eham.net/ehamforum/smf/index.php/topic,85363.0.html

I started the thread, but I don't see it that way (as being hijacked)
Though I started the thread, I have no delusions that I "own" it. It is owned by EHam, not me. It has had nearly 4000 Views, so evidently it has provided some entertainment for a bunch of bored older guys (like me)  Wink

My only regrets about that thread is, I lack the technical knowledge to hang with the guys debating in the thread.
I am not "territorial" about any threads I start. If I don't like the way a thread I started is going, I can simply "QSY" and start another one.
Though I did not technically understand all the points of contention in that thread, who doesn't like a good, vigorous discussion ?

Ka7niq Yes invigorating. The 43 ft vertical offers plenty of utility and certainly benefits from a counterpoise, 1:1 current balun and a network all located "at the vertical base.

I am using one at a summer cottage and evaluating it in real operation as opposed to the virtual modeling aid.

In my system I have designed provisions to quick change the (wire) vertical element from 43' to either 66ft or 22ft. The wire is held up via a tag line rope over a tree limb and dead end ground anchor easy to do.

this technique allows the user to operate the vertical in a range from the 1/4 wave to 5/8 wave.
IE the 22ft is on  10m=5/8 to 1/4 wave beyond 20m. Always where the length is near a 1/2 wave use caution and pay close attention to the output power because the end fed half waves are stressful AT the tuner and balun. Mine is not an end fed zep because I use tuned radials and believe this is now a close to center feed antenna. It is the higher feed point impedance's that can be problematic with respect to high voltages pressuring the tuner and balun.

My system incorporates an auto tuner L network and pairs of ground isolated and insulated tuned elevated radials 2ea.sloping downward in opposite directions for 10m,12,15,17m,20,30,40m and could continue on for the lower bands. The radials are intended to not radiate and can be close to the house and paralleling the structure. The distance the vertical exits the window sill from the roofline is about 6ft and the vertical slopes upward and away at about 5 degrees minus straight up.

The advantage of limiting the choice to the 1/4 wave to 5/8 wave range in operation on the air is for the manifestation of power in the lower angles for more assured longer range HF dx work. as a function of pattern development.

The cost of this antenna system is $249 and $50 for everything else.

The tuner is remote controlled and just inside "at the interior of the window sill"  and the 1:1 current balun is installed on the ouput of the tuner so-239 using a male to male UHF adapter both being weather proofed and then the radials and antenna element connect to the 1:1 current balun terminals accordingly. The 1:1 ratio is intended to remain stable and not be an impedance transformer in any direction while greatly attenuating common mode displacement currents and forcing both equal and opposite differential mode voltage and current RF between driving the shield (counterpoise radials ) equally as driving the antenna element(vertical) for best return and minimal ground radial system return loss to the vertical proper.

Since the tuner presents a matched condition for the line back towards the equipment that coaxial cable can be longer devoid of problematic mismatch losses and would lend itself nicely to placing the equipment in another room.

I attach a wander lead outside at the antenna base to a safety ground rod (takes the antenna to the outside ground rod) and disconnect the equipment totally from the wall outlets when expecting stormy weather.

I am very impressed with the systems utility as a longer hf dx work antenna.and was able to build this for a price comparable to a trap vertical.

I honestly think this approach can rival or even outperform a trap ground mounted version.

Mine can be a little better moved farther away from and more out in the clear.

This design reveals that there are cost effective solutions for the trapless vertical operated at 200 watts pep.

I have used many beams up real high and am not comparing the two.

Being accused of so-called "hijacking" of a thread appears to be a diversion akin to George Bush being blamed for the state of the 2012 US economy.Smiley

If the thread drift is not interesting then the new thread will die on the vine.

If the thread drift is interesting then the new thread may thrive and sometimes elicits more postings that the original thread subject. There's always room for one more interesting thread.
