Best coil design for surf PI

[39cents]

Does a basket coil still require a shield to reduce effect of ground capacitance?

doing from fiberboard, take two nails and lath, cut by them. hammer nails in wood lath on one radius size, cut,
do same with another radius size. you get the ring.
then cut slots.

check the word i give a pic

I mean the coil pcb...

There is no PCB for the basket coil. It is a cut frame. It is all explained in the link that I posted for you above....

Anyone sell pcb’s for this (in US)?

Here is a kit from the US, obviously not the same Long Board layout.

You might be better off just getting a PCB from Silverdog.

If you have not already done so, you should give this article by BBsailor a thorough read. It contains virtually everything you need to know concerning making a simple mono-coil.

good but not had actual in modern time. we mean FASTEST BACKET coil.
yes, new matter for you. unknown for you. sometimes DUAL FIELD BASKET coil.

Hi, I am planning to build a mono coil for a surf PI that has a diameter of around 10 inches. Are there any key factors that influence the depth? I am aiming for a coil inductance of around 400uH. Should I try and maximise or minimise the coil resistance? i.e. should I use thin or thick enamelled wire? What about the winding capacitance? Is this a big deal?
