Topband: Radial plate

[Charles Moizeau]

With in-ground, which optimally should be be so shallow as to be on-ground, radials there's no thought or effort needed to think about them as being anything close to the intended radiation frequency.


But with elevated radials my understanding, and it is more nonexistent than limited because I've never tried them, is that all have to be physically matched to one another yet tuned to the radiation frequency, and this requirement is an extremely fiddly undertaking because there will be nearby objects, e.g., trees, varying ground slopes, etc. that will differently affect radials of identical physical length.

Hi Carl,
One advantages of going underground. No more wires hanging up in the air. It
will look cleaner. But I do not have any idea if my signal will degrade
going with buried radials over the 5 elevated radials at each feedpoint. The
ice was brutal this past winter.
Why do you say there will be a large signal loss going from elevated to
ground radials? You got my attentions with that statement.

Since the change to on ground radials can result in a large loss of signal
in some areas why not just invest in stronger elevated radials?

I use scrapped deep well wire from well shops which is available in #12 to 6
in this area in 2 and 3 wire insulated styles and is often free. . For the
16 160M radials up 12-15' they run over tree branches and also over fairly
open areas.

Since I live on top of  the tallest hill in the area of Southern NH  Im
exposed to everything Mother Nature can throw at me from all
directions.....ice included. Back when I used #18 & 16 it was regularly
needing repair, amd now nothing in about 12 years. It acts/handles like a
cross between soft drawn house wire and hard drawn.

#16 to12 copper clad steel is available also with and without a strong
jacket and stranded or solid..

Planning on changing from elevated radials to ground mounted radials for my
80 M 4-sq. After twice having to rebuild the elevated radials this past
winter from the snow/ice storms it is time to go to the ground. I plan on
having the feedpoints on 4x4 posts with the feedpoints 3' up from the ground
so they don't get snow covered often.

Looking at the DXEngineering Radial plates. It looks like an easy way to tie
the radials together on the ground then run a ground wire up to a box at the
feedpoint. Any comments or issues with using these radial plates?



Also going to use buried feedlines - RG6, ¾ wave with 8 turns through #31
big clamp-on core at the feedpoint.

73,
