Default Re: New long wire AM aerial and switching box

You might be able to improve it even more by placing a 100pF variable cap in series with the aerial and tune for maximum. It may also be worth trying an ATU (Aerial Tuning Unit) which is a bit more complex using a coil tuned by a variable cap. Various designs can be found via Google
