I’m going to knock up a single band inverted vee for 20m and I wondered if a knot in the wire near the feed, to act as a stopper for a cable tie would have any negative effect?
It would be very near the feed point.
Also, are egg insulators essential at the dipole ends? I was planning on using nylon cord (like the thin white stuff sold for hanging pictures) to peg out the dipoles, so that would be several feet of insulation surely?
And I intended tying a double fisherman’s knot at the end of the dipole to attach the cord, leaving a tail of wire for tuning. Would that affect performance /tuning?
