Subject: [TowerTalk] Cushcraft R7
I currently have an R7 mounted at 8 feet above the ground. The SWR curve is
as advertised, however from time to time the SWR goes through the roof on
every band.
I had the antenna down recently to repair the 40 meter portion and inspected
it, but I cannot find anything loose or broken. This doesn't seem to be
weather related.
I sent an email to Cushcraft about the problem but only got a "canned"
response back.
I suspect the "black box" has a problem, but since Cushcraft no longer
supports this antenna (even though it is only 6 years old) I am not sure
that I can replace it.
While I am not a big fan of this antenna, it is currently the only one that
I have up for HF.
Any ideas?
