Im slightly puzzled by your last statement. Why will twisting it have any
affect?

Twisting tends to expose both transmission wires to the same environment.
For instance, if you ran one wire 0.5" away from sheet metal and the other
wire 1.5" away from the same metal, you would unbalance your currents
because of the metal's effect on the closest wire.

Thnaks Dave and Cecil for your explanations, it now seems to make sense to
me.

Greg,
Aside from the electrical affects of twisting the
twin lead you also have the benefit of making it less
affected by wind. It 'flops' around less than if it
wasn't twisted. Ever noticed how the 'tape' advertising
thingys are really affected by wind if they are ~not~
twisted?

Thanks Doc. This is is all very useful information I will bear this all in
mind when I am making up my next antenna. That's one good thing about this
hobby there is always something new to learn.
