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.

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

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.

The question was not the soldering iron...how did you regulate the
temperature of the secretary?

Jim


I was using one at a bench when a secretary asked me what the
knot was for. I told her that's how we regulate the temperature
of the iron - the tighter the knot, the fewer the electrons
getting to the heating element. Physics was not her long suit.

No, no, no. If you put in a 20 knot watt, you can't run fast enough to
catch up to it.

Jim


Ok, Ken, just make sure you put in at least a 20-watt knot, so you'll have
a little margin to spare.

Nope!unless it might be mega-kink per inch sq....hey; mega-kink per
inch sq. that might wind up being something close to 1.5" copper pipe
which would be great. Just figure up some means of support for it.
This is a winner Ken. We can name it the Kenneth Kilo-Killer-Kink.

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.

I don't like to think of it that way...
I think it is more like I am "pardoning them" after they have served
their sentence... and once again they are free men... err, free
bacteria...

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