Hi! This has been nagging me for a while, and any antenna design resource I've consulted doesn't really seem to cover it.
When making a wire antenna, one can't avoid having a knot at the ends. likely at the feed point as well, if it's a dipole or such.
How do you calculate wire length, then? do you count the wire in the knot, or loop, if U-clamps are used, or does the knot have so much choke effect, that it can be disregarded all together?
Of course you could just make the wire a little too long, and then test it, and trim it for optimal length, but since I'm mostly dealing with receiving antennas, it'd be nicer to have a rule-of-thumb or two behind me.
Thanks in advance!
