Hi Jeff,
Will pass your email on to the 160 meter topband reflector. Africa has much
noise, & not many noise free areas. Unfortunately your QTH is not in one of
them.
Noise is additive, so the right directive antenna will help.

Hi Bruce:
I had lunch with Laurent Miglio
The problem most likely is not the raised radials per se.
That he does not have space for buried radials most likely means he also
doesn't have space for full size, dense and uniform all around raised
radials either.
Without details, but after 5 years of hearing about what people have
actually do
YES! With elevated radials, a good common-mode choke at the feedpoint is a
must! I used a design from K9YC's RFI PDF.
IIRC, about 6 turns of coax through 5 stacked 2.4" #31 cores.

Common mode choke, and maybe a relay to disconnect feeder from inv L and
raised radials.

Have a friend that is getting noise from raised radials connected to his
inverted L antenna.
He can not bury the radials due to space problems.
Are there any recent solutions to the problem.?
Thank you in advance for your input. .
