Hi Kelvin!
Yesterday I put a mere two 7' radials on the antenna, and now it's working!
: ) These are the only radials on it right now, but this morning I am going
to add two 43' radials. For now, I am doing it sloppily (eyesight). When
my friend comes back to help me, we'll make it tight and right.
Progressively, I'll add more and more radials. With just these two 7'
radials, it can tune between ~ 10M - ~40M.
73,
Richard KK6MRH

Effect of Radials on SWR
Hi Richard,
Putting down radials is good! In effect, you are trying to hide the lossy
ground from the antenna, so the return paths are at an absolute minimum. If
your radials are laid on the ground or more commonly buried by a few inches,
they will be detuned, and so cutting to a resonant frequency is somewhat
unnecessary. If your radials are elevated, then resonance is important, but
I don't know about multi-band verticals <smile>, I guess you need to have
resonant lengths for each band. I don't know what space you have available,
but just get as much wire down as you can.
In answer to your question, yes, the addition of radials will certainly
change the SWR and improve the performance. I would forget connecting to
the neighbour's fence, as this will do nothing for either RX or TX.
On the 43 foot vertical, I seem to remember the complete 6M to 160M range
was not available, without lengthening or shortening the antenna. I think
you needed to decide if you wanted 20M through 6M, and these bands would not
tune if the maximum length was used for 160?

Hi Steve! Your question (below) about my radial system leads me to ask
everyone the following question: Is SWR affected by radials? Presently, I
seem to have some trouble successfully using the TS-2000's internal antenna
tuner. I seem to always get a "SWR" CW squawk : ( I *think* I should get
an "A" CW squawk when the tuning was successful. Isn't that right? The
following is a bit more background.
Right now, *no* radials are laid-in. I have purchased all the materials for
my radial system and made a plan, but I have not yet had time with my
electrician friend (sighted) to lay it in. So far, just getting up this 43
foot 160M - 6M vertical and laying in the ~75 feet LMR-400 coaxial feed line
has been a fair amount of work. My radials will be the final step; and that
should happen within a few days. The radial system *will be* the following:
* 10'X4'W 19 gauge galvanized steel industrial mesh, centered at the base of
the antenna
* 4 ~43' 14 gauge shielded copper wires
* About 8 ~7' random length radials like the last item
* I may also connect to my neighbor's adjacent chain link fence ; )
For now, I cannot even tell you what, exactly, my SWR is. My wife (sighted)
cannot understand how to read the SWR meter (girls ; )). I will need a man
to explain it to her; so she might then be able to tell me what it says if I
were to ask her to read it for me.
All of the foregoing are, I suppose, a result of my inexperience and normal
learning curve growing pains attendant with being brand new to all this : (
So, all the advice I can get is greatly appreciated.
73,
Richard KK6MRH

Richard,
Just curious. What kind of radial system were you able to put under the
vertical?
