Topband: Flag Antenna Feedline Decoupling

[Michael Tope]

I am getting ready to build a set of flag transformers and had plan
to put a string of ferrite beads on the feedline to decouple it from
the antenna. Can anyone tell me how many beads I should use to
get adequate decoupling? I will be using Amidon FB-73-2401 beads
(ui = 2000, thickness 0.2"). I was thinking that 25 would be a good
number (~300 ohms series impedance at 1.8 MHz).

Thanks,

Mike, W4EF..........................................
