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

[Jim Lowman]

Background -

QST Magazine, and various commercial entities, tout the benefits of a 
1:1 line-isolation balun - sometimes simply made by slipping a number of 
ferrite beads over the coax feed lime. and securing them with heat 
shrink tubing.   (e.g., Palomar Engineers, BuxCom, and other vendors 
sell these as an inexpensive kit.)

Several articles and commercial vendors suggest using line isolation 
baluns ( which are often made of ferrite beads)   on  feed lines in the 
shack - including the short jumper cables running between rig and amp, 
and between amp and tuner,  and so forth.

Questions -

1)   What if I put those ferrite beads on ALL my coax jumper cables as 
they run between rig and amp and tuner ?   Any downside to this ?

2)   What if I installed those beads on outside coax cables, at the feed 
point, as suggested in the many articles I have read.   Any downside to 
this ?

3)  What if I do both  1)  and   2)...   and install them all over the 
place ?

              THANKS in advance for your insight.
