The Knot matters not
your signal will live
but the receivers
will need to tie
a knot in their ears

Does a knot in insulated 16g stranded wire pose a problem
for a dipole at HF freqs? This is a 66' FD dipole, coax fed,
operating 40-10m with a KAT2 autotuner. The knots are 1/2"
away from the feedpoint & lock the antenna to it's center
insulator.

Only if it is tied really tight. The electrons can't make sharp turns at
C*VF and end up somewhere else.

I just had an idea - I could strip 1/2" of insulation
just past the knot and solder a jumper to the feedpoint,
electrically bypassing the knots while still leaving
them there to be strain reliefs.

Thanks for the help, guys.

They flp off the sharp curves and fall to the ground where
they lay writhing until they expire.

Ken:

Some of like to joke a bit, we mean no harm, please do not take
offense... I really believe the general consensus is that the knot is no
problem...

.... now, that said, to tell you the truth, the knot just being there
would bother me--and I think it does you too--I'd probably remove the
knot and go to great ends to do it--but really, the knot matter
naught...

Warmest regards,
John

I think John is right
Even though the antenna will work fine WITH the knots
if the owner of the antenna has doubts
then the knots should be removed post - haste.
all you need is that element of doubt
when you can't quite get thru the pileup.
Was it due to those 2 knots ?
Yeah - solder a jumper - or untie them for sure.

A knot in an antenna wire will have absolutely no electrical effect
below about 200 MHz.

But it will mechanically weaken the wire. During the next hurricane or
loading with ice it will be more likely to break.

Your answer is surely correct, but not as interesting as the other
threads.

Buck, may I suggest replacing "interesting" with "useless".
