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 |

CECIL!!!!
ROFLOL!!! Hey, I got some change here, how much you got, wanna go halfs on a new bottle? grin Warmest regards, John "Cecil Moore" wrote in message ...

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...

The RF gets all tied up in them and doesn't know which way to go, so the power concentrates there and pulverizes both the wire and the insulation--the knot goes pooof! And down comes the dipole. How much did you say you paid for it? Walt, W2DU I didn't pay much for it. I had the coax & connector plus the center insulator. The wire was $3.30. FYI I'll only be putting 5-15 watts SSB/CW through the antenna on FD. Ok, Ken, just make sure you put in at least a 20-watt knot, so you'll have a little margin to spare. Walt |

You should be doubly guilt panged, Cecil, just think of the billions of poor yeast that gave up the ghost to assuage your guilt.

That's assuming 1 trib - electron, multiplying with an average litter of 10, producing a new generation every 12 hours for 3 days. Cudos to Cmdr's Spock & Dax - does that label me a Trekkie?

How much did you say you paid for it? Reminds me of my youth. One of my earliest jobs was working in an automotive parts store. This was back when you actually had to know cars and how to read and look things up in paper catalogs and stuff like that. One test some of the oldtime mechanics would do on a new parts guy would be something like asking for a set of spark plugs for a Cummins diesel, a radiator cap for a Corvair or a pan gasket for a Powerglide transmission. I fess up... they got me on the last one. Ken, the only problem with the knot is that the wire will be weak at that point. |
