??Hello Eduardo,


Sorry, but I don't have any of his formula's.

But I send this reply in cc to the RSGB LF reflector, maybe someone can hel=
p.

Hi,

I have been reading some sections from your page on 136kHz
http://www.strobbe.eu/on7yd/136ant/

Very good write up, many thanks for making it available. I am not really in=
to 136kHz, but I landed on the page looking for ways to model a helically w=
ound antenna. You give some equations for inductive loaded antennas and I a=
lso see many references to G4FGQ pages.

I am also familiar with the programs that G4FGQ wrote to calculate helicall=
y wound antennas. Sadly he is SK, so finally here is the question, would yo=
u know what equations he may have used in his programs?

Many thanks in advance,
Eduardo, M0KEK
