Only if it is tied really tight. The electrons can't make sharp turns at
C*VF and end up somewhere else. .. "Ken Bessler" wrote in message news:Q64oe.9868$Wr.5569@fed1read04... Does a knot in insulated 16g stranded wire pose a problem for a dipole at HF freqs?

... 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. -- Just my 2¢ worth... 73's es gd dx de Ken KGØWX Grid EM17ip, Flying Pigs #-1055, Digital On Six #350, Proud builder & owner of Elecraft K2 #4913 |

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...

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. "John Smith" wrote in message ... Ken: Some of like to joke a bit, we mean no harm, please do not take offense...

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. ---- Reg, G4FGQ |
