Feeding a Folded Dipole
I have a folded dipole coupled to the feed line with an Icon AH4
antenna coupler. That has worked rather well for me in my rather
random pattern of operating. The folded Dipole is a Barker &
Williamson BWD-90 from which I removed the Balun and the center
resister. I then shunted the resisters previous location. I had
been feeding the modified BWD-90 with window line from the terminals
of the AH4 coupler so as to allow the antenna to remain more nearly
flat. With the weight of the balun, the terminating resister, and the
coax on the center of the antenna it drooped quite a bit. I took out
the resister because so many people told me that I would never know if
I was getting a decent signal out or just warming up the resister. If
I should not have shunted out the resisters previous location I would
appreciate not just "don't do that" buy why it is a bad idea.
My problem is that I would now like to use a Yaesu FT-1000 that a
fellow club member has loaned me and I have no way of controlling the
AH-4 because the adapter that I was using with my Yaesu FT-857D will
not work with the Yaesu FT-1000. I am open to any suggestions
providing that they can be done in a yard that allows me only a ninety
foot span between supports. I suppose I could save up and buy a new
coupler but I was hoping for something a little less costly.
Should I give up on using the modified BWD-90 for now and put up
another antenna? I could buy a fan dipole I suppose but I need a way
to feed it that does not require a heavy balun up at the feed point if
possible.
K someone please
