I want to thank everyone who responded to my question about radials. For
those who are new on this list - ASK QUESTIONS - you will get answers.
Not only did I get answers but I got good advice, and education I
couldn't have paid for and I had a great time.
THANKS AGAIN FOR ALL THE HELP. Per the advice of some I looked in an
ARRL antenna book (15th edition) on page 3-13 Table 3 lists Optimum
Ground-System Configurations - for 16 radials (about what I have room
for) it suggests they be 0.1 wavelengths long, with a 3db loss and will
give me a feed-point impedance of around 52 ohms.
This agrees with a lot of what I was told and disagrees with other things
I was told - Aint radio great - everyone was correct.
I have one other question - I think I know the answer - Okay, I now have
radials evenly spaced around my vertical (ya right) but my son goes off
to collage and I would like to maybe direct my antenna towards him. If
I run a longer radial (1/4 wave) in his direction, from what I've read,
this should put a lobe in his direction. My question is - does this
achieve this by (1) cutting back on my power going to other directions or
by (2) reflecting more power from the ground and giving me the lobe. I
think, from what I've read, that #2 is the correct answer. How about it
teachers - do I get an "A" or an "F".
Thanks again.
