Reg:
I think you quite correct--we should not be thinking "knotty thoughts" anyway... grin Warmest regards, John "Reg Edwards" wrote in message ... 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 Buck says politely - Your answer is surely correct, but not as interesting as the other threads. =============================== Buck, may I suggest replacing "interesting" with "useless". ---- Reg, G4FGQ |

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? At one place I worked in CA, we put a knot in the AC line of our soldering irons and hung them on cup hooks on the wall when not in use. 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. Did she look OK in a short suit? :-) |

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.

Every day when she left work, the R&D engineers would gather round the window and pray for the wind to blow. -- 73, Cecil http://www.qsl.net/w5dxp ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |
