I'd stay with the elevated radials,Bob! They're hard to beat! For some
years I had an 70 ft tall inverted L at a back corner of my lot. I had only
two elevated resonant radials 90 degrees apart on the back and side lot
lines . I worked lots of stuff in Eu, middle east, The Pacific, Indian and
Atlantic oceans with 500W. 3B8, S7, KH6, KH5K, FO0, KH2, KH0, JA, VK, ZL,
ZD9 etc.. Generally if I could hear them on my KAZ antenna, I could work
'em. BTW, if you run radials in your crawl space, you risk coupling energy
into your house wiring from the close proximity radial currents.
Good luck

Subject: Topband: Radial Question
Hello Fellow Topbanders -
We are about to embark on a front yard landscaping project at our home on a
tiny 12, 500 sq. ft. lot.
It occurred to me this would be an excellent opportunity to put down a large
number of buried ground radials BUT, they would only cover about 90 degrees
of the compass. Then it also occurred to me I could put down a large number
of radials in our crawl space under the house.
So, my question is, what is the likely negative impact, if any, from the
house being between the 160 meter vertical and the radials placed under the
house? I assume the house material, most of which is wood, tile, sheetrock,
etc. (with the usual house wiring) would be invisible to RF and have minimal
impact.
If I could put down say 60 radials ranging in length from 40 to 120 feet
long, would it outperform my current system with 8 resonant elevated radials
10 -15 feet high (which cover only about 120 degrees of the compass)? I'm
incline to proceed IF it would provide a meaningful improvement in my
transmitted signal strength.
Thanks for any help!
73,
Bob/AA6VB
