Hi Guys,
Thank You for the many replies... I appreciate it!
Update: Gene and another ham replied that I could simply add the reflector
and NOT connect it to the driven element or the transmission line. Since
time is short before tonights CQWW-RTTY contest... that's the installation
method I used. The spacing probably isn't optimum as I had to mount the
reflector 35' behind the driven element. (it's on a dock and that's the only
available mounting place). But the reflector is SW of the DE so at least
the 2-element vertical should be beaming NE (Europe) which was my goal.
I expected SWR to change with this setup but that was no change in SWR.
Perhaps my reflector is too long at 35'6" ... do you think I should shorten
the reflector or leave it as-is?
I'll post a reply tomorrow and let you know if I noticed any difference in
Gain or F/B.
73,
Dick- K9OM/4
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.
