[TenTec] [Fwd: Line Isolator Balun (sorta) question.]

[Stuart Rohre]

If you put them on ALL cables the ONLY downside is you will be a poor man!

They are only needed to block RF on the outside of the coax, IF you have 
RF on the chassis in the shack; OR if you have a dipole you are feeding 
with coax; OR if you have a tuner (T tuner) that you would like to use 
to feed balanced feedline.  You put a cable choke of beads on about 1 
foot of coax between the tuner and the ladder line or twin lead, and you 
have forced balance sufficient for the task.
