Hi,
Need to make common-mode choke to give maximum impedance at 28 MHz, coax
is RG-213, but unsure of Fair-Rite part number for mix-43 toroids (order
would be to mouser, so an appropriate part number from them?).
I've read the YCC article (2006?) by W1HIS), but needed clarification.
Any advice appreciated.
Thank you
Steve

I was under the impression that a Yaesu G-1000DXA would control a Yaesu
G-800SDX rotor.
Am I mistaken?
If it is possible can anyone tell me how it should be wired since the
1000DXA uses 6 wires and the 800SDX uses
only 5.
If it can't be done I have a good 1000DXA controller for sale/

They are interchangeable however you will need to build some kind of
pigtail
to act as a connector/gender changer to go from DXA to SDX or vice versa.
The manuals, with schematics, are available on BAMA.

The last post on Yaesu rotors got me think about a question/need that I
have. Does anyone know where I can get the Male 6 pin Cinch Jones plug
for the controller (6 pin). It appears to have 5 pins that are
horizontal and 1 that is vertical. I've looked all over and cannot find
it on the internet. Mine got lost/misplaced in my move.
Thanks

Per EZNEC+ 5.0.59:
80M vertical over "real/high accuracy" average (0.005, 13) ground
1 radial 0.5' above ground gain -2.07 dBi "front" and -5.59 dBi "back"
1 radial 10.0' above ground gain -0.16 dBi "front" and -3.71 dBi "back"
So, yes there is a difference in gain between "front" and "back" (toward
the
radial and away from it).
Looks like if you are going to have only 1 radial you'll want to elevate
it.

Once again I read an article in a ham magazine about a vertical antenna
with one radial. Claims gain in the direction of the radial and null off
the back. Where is this in reality?
This wouldn't happen to have been the CrankIR review in QST, would it?

Subject: [TowerTalk] Rotor control cable connectors
Message-ID: <53791CC2.3060101@windstream.net>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
I was looking for connectors to add to older HY-Gain rotors using 8
wires. My new production unit came with connectors but the older units
use an 8 position terminal strip that is not so wonderfully weather
proofed. So you get your unit refurbed or it is still working fine but
still has the old terminal strip... not satisfactory...
So I'm searching Mouser, Digi Key etc and then... and then... the
little over my head light came on, dimly but noticeably illuminated.
Flat 4 pin trailer connectors for hooking up the lights on a trailer to
be towed. Need 8 pins. Connector has 4 pins. One side is 3 males and a
female and the mating connector is 3 female pins and a male. Take one of
each male and female and using the supplied pigtails put on ring
terminals and install the pair of flat connectors to the terminal
strip. Flood the terminal strip with Silicon rubber (RTV) or your
favorite weather proofer and put on the cover. Another pair of
connectors terminates your cable run at the rotator end.
This gives you polarized connector action. You can't plug the cable run
from the controller into the wrong connectors at the rotator. The
trailer type flat 4 pin connectors are made to be exposed to the
elements in their normal application. I like belt and suspender type
weather proofing so... Wrap the connectors with tape or coax seal or
whatever you prefer to boost the weather resistance if you are worried
that these inexpensive connectors could do a good job. Electrical tape
and a little RTV does a marvelous job and is easy enough to remove if
the need arises.
I kinow, I know, no material certs, no mil-spec, NIH, too inexpensive to
be good etc etc...

============================================================
I response to the many requests, I have replacement OEM cable connectors
for Yaesu Antenna Rotors & Controllers. Yaesu models:G-450A, 650A, 800A,
SA, DXA, 1000A, SA, DXA, 2800DXA, 5500 and many more. Available are the
small rectangular ELP & R-06V, 6 pin connector for the controller and the
round metal 7 pin connectors, NJC-207-PF, -RM & -Adm, and the 6 pin,
NCS-256-P, cable/rotor. For both the cable and units. Mating connectors
are
also available for making cable extensions.
I also have connectors available for use with many of the Transceiver
Antenna Auto Tune functions on the TS-50S, TS-480, TS-570, TS-590S,
TS-850S
ACC4, TS-990S, TS-2000, TurboTuner, LDG K-OTT and many, many more.
