Hi I wish to hook up my G5RV so that the centre is on my mast and the legs
go one to my chimney, and the other to my neighbours chimney. the mast from
both chimney's is about 55 feet. the two chimneys are about 50 apart. It
will form a V with the feeder at the mast. Will it work or is the angle to
tight

Thanks in anticipation

Peter

Egad, how big of a job could it be to put it up and try it?

I will go so far as to say that even in the configuration that you described
(original poster) it will easily outperform any $400 to $500 multiband
vertical antenna that you can buy (figured on the highest average
performance on the most available bands). Good enough?

I thought the feedline could not be near the METAL mast... Am I wrong?

So use PVC, or some other work around.

If you are using the popular 450-Ohm window line you need only keep
the line 2½-3 inches away from you mast. Additionally twist it a bit
(about 180º every couple of feet) and you'll be fine.

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

It exposes both sides "evenly" to the mast, reducing proximity effects.

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?
