Greetings Topbanders:
When I initially started researching researching the information to
build my K9AY type array, the recommendation was to use a toroid with
#43 mix which I did. Now as I read my new 4th edition UN4UN
Lowband DX book (Thanks SantaMama) I see that the recommended mix is
#77. Without placing an order to Amidon I have available to me for
immediate use, various sizes toroids of #31 mix and #43 mix. I also
have some of the small toroids( General BBR 7731) recommended in the
older version of the Beverage Antenna Handbook(Second Edition).So,
please, the questions are:
1) Who is using what mix? What are the results with each?
2) How much difference will a different mix REALLY make?
3) Is it worth the effort to order new toroids with #77 mix?
4) Does anyone know the mix in the General BBR toroids?
Many Thanks,
73,
Mike, W5UC
