Author Topic: Splicing wire in a dipole question  (Read 1156 times)

My dipole had an unfortuate encounter with a neighbor's tree branch on Wednesday evening during a storm, and is now going to require some repair or replacing.  One option is to fix it by splicing a few pieces of copper wire together.  This is the cheap option.  However, could this cause problems later on?  I am wondering if the junctions of the wire could corrode and start acting like a diode, throwing out RFI all over the place? 

Could this happen, or is splicing copper wire in a dipole usually ok?

Splicing will be fine, I just tie in a knot, hi

You could also solder it back together, use butt connectors and crimp them together or even tie them together.  I've done this many times with no affect on performance.

To some extent the answer depends on the type of wire.  Solid copper shouldn't
be a problem - use a lineman's splice.  You can then solder it to help maintain a
good connection.

Bare stranded wire can be an issue, as solder will wick between the wires and
make it less flexible.  That can cause eventual failure if the wire often flexes at
that point.  Again I'd use a lineman's splice, but solder only the middle of the
splice where it isn't as likely to flex.

With small stranded, insulated wire I often find that the insulation provides
more strength than the copper itself.  In that case tie a good knot in the
insulated portion to take the mechanical stress, leaving enough length on
the ends to bring the ends together to make the electrical connection (solder
will help it last longer.)  I often use a sheet bend or variant for tying the wires,
as it is fairly strong and simple to tie.
