I had a lot of RFI with my OCF dipole. This was mostly eliminated by the
addition of current baluns (RF chokes) at the antenna feedpoint and transmitter
in the shack. I like the chokes made by Palomar.

I have that same antenna. Nothing to report though. I am experiencing a lot of
RFI. Plus I am lacking a satisfactory radio to test with. I chose the OCDP
because it spans most of the bands. But also it offers some geometry advantages
being 1/3 on one side and 2/3 on the other. I g reasonably good SWRs. I Another
supplier uses a 70/30 split. I would check your OCDP with a nano-van to see if
it performs at the frequencies you want. Mark N5PRD

Rick,
I put up a 80 M OFCD from my chimney. I put the Balun on top of a 10 foot
fiberglass rod strapped to my chimney top cover. That gets it to about 32
feet high at the apex of the inverted vee. So far no complaints from the HOA
Gestapo. While it is visible from the street, it is vey unobtrusive, and just
looks like a 4” X 4” box mounted to my chimney cover. If the HOA asks I plan
to tell them it is an atmospheric monitor to make sure the air quality is good.

Hi Rick,
Since I don’t have any personal experience with that particular antenna I can’t
comment on the build quality.
But I do have an OCF dipole with a 4:1 balun cut for the same bands in an HOA
situation. Mine is at 25 feet and I’ve been extremely happy with its
performance. My furthest SSB contact has been Bosnia on 20m. It’s no beam but
it gets the job done! It’s been up for almost a year now and I’ve managed to
avoid the HOAs attention. For mine I’m using black insulated wire with the
balun hung from my 2 story chimney on a pulley and each leg of the dipole
running to two trees.
If you want to go super stealth I’d recommend building or purchasing a 4:1
balun and using some Davis RF poly stealth wire. It has a very high strength to
diameter rating. https://www.davisrf.com/antenna-wire/polystealth.php
If you feel that the MFJ is going to work for you I’d say go for it based on
the reviews. If it ends up not suiting your home QTH, well, now you have a
portable antenna!

I acquired a Kenwood TS2000 through this forum a few months ago, and have been
browsing around for a first antenna.
There are almost too many resources for discussion and recommendation, a very
nice problem to have.
Based on a number of comments, including remarks by Dave Casler in his Youtube
channel, I’ve landed on this:
MFJ Ultra-Lite Off-Center Fed Dipole Antennas MFJ-2010
I’m not exactly sure yet how I’ll get it 35 feet up, but that’s a problem
regardless of which antenna, unless I go with a tower. Living under an HOA in a
gated compound, I prefer to see if I can get by with just the wire and make
that “inconspicuous”.
If anyone has a strong conviction that this is just the wrong thing to start
with, I’d love to know why and what you would recommend instead. Keep in mind,
this is not the only antenna I will buy that, just the first.
Thanks, all.
