[bars] Measuring wire antennas

[Jim Idelson]

The 'effective electrical length' of the wire is influenced by several
parameters. One of them is the physical length. Others include the type of
wire, the insulation and the height above ground. Hard to know what that
little loop from the main wire to the balun will do. You don't actually
know that electrical length for sure until you measure it with a signal
applied from your antenna analyzer or transmitter.

So, here's the Pro Tip: *Always make the initial cut on the long side - a
good foot to eighteen inches.* It's a whole lot easier to trim bits off
than it is to add length of you cut it too short.
