Hi all,

Wonder if any one has compared the doublet fed with open wire line to
dipoles cut for the required bands.

My two bands of interest are 160 and 80 metres.  I am using a doublet
with a top of around 230 feet.

I was talking to a friend today with a similar setup on 80 metres.  He
went and cut the extra ends off and made it 132 feet in length and his
signal was reported some 10 db improved.

So, I am concluding that it is possible for a doublet to be too long and
the old saying to get as much wire in the sky is not always true.

So, just wondering if anyone has made meaningful comparrisons
between the doublet and dipoles.  What about the F7FE idea of feeding
more than one dipole from the same feeder?

My activity is devided between the two bands and I do not need the
aerial to work on any other band.  I had thought of traps but I use a high
power linear and would not wish to melt them.
