Hi Dick -
If "easy"is important, it might be easier to just put up a parasitiec
reflector. Resonate at 6.7-6.8 MHZ and place about 25 feet behind your
present vertical. It will affect your SWR but if your Xmtr will tune ok and
your feed line isn't too long ( lossy) you should be good to go. Without a
lot of fuss your gain and f/b should be about the same as driven two
element.
