FT-240-43 FT240-43 Ferrite Toroid Core 43 Material

I got two of these for my 40-6 meter EFHW. They are at both ends of the coax with 6 turns of the coax and it tunes up fine on all the bands

I have not tested in a circuit yet, but seems well constructed. It is very similar to other toroids that I have used.

I built an antenna for GMRS and needed to stop the common mode current. Prior to adding this as a choke my feedline had an SWR that floated from 1.2-1.5. Adding this with 6 wraps of coax near the antenna worked amazingly well at stabilizing the antenna system.FT-240-43 FT240-43 is the ferrite you want for UHF

This ferrite ring was perfect for building a 'common mode' current choke as used in amateur radio transmissions lines. It is large enough to accept up to twenty turns of RG-58X coaxial cable.

I needed an FT-240-43 toroid to construct a common mode choke. This fit the bill and the price was right. The toroid arrived undamaged, although the packaging looked sketchy. The vendor could do a better job there, but this is a review of the product, not the vendor.I have no way to test if this really was a mix 43 or not, but it definitely was an FT-240! NI have no reason to believe they didn't ship ne a mix 43, but it would be nice if it was marked in some way.I wound my choke and my common mode noise issues went away, so the toroid (or is it a toe roid?) did its job.

Recently, every time I order Amidon cores through Amazon, Amazon gives me a promise date (typically 2 days) but it always takes longer. This was no exception. It was late.

Used to reduce the flickering caused by a Rheem tankless water heater. I could probably use another wrap, but they're working good enough for now.

Esta es una ferrita FT 240-43. Y cumple con los requisitos. Construí un choke para HF y funcionó como se esperaba. Se recomienda.
