OK, I purchased the Imax-2000 which is a 5/8 wave antenna. There are 2 options
for a ground plane kit:

1. First is a four fiberglass 6 foot radials, angled down (appears 45 degrees),

2. This is another kit. It has four aluminum 7 foot radials. This is horizontal,
and not angeled, as seen he

Which one would be better?


You should give Frank's suggestion a look as it does contain a lot of
information on antennas.

But to answer your question, your particular type of antenna, like the
A-99, is designed to decouple with no radials. Adding radials to this
type of antenna does very little to improve performance. It's more
about marketing hype than actual performance improvement.



I should have been clearer. I wasn't trying to improve performance, since it is
a 5/8. But from the reading I have done (no thanks to anything Frank posted), I
was simply seeing if thise would lower the angle of radiation, and reduce
potential for any king of interference. I am sorry id my lack of knowledge in
this field, insults Frank.
