Not that I'm aware of. I think TED created that connector
for King radio way back when and it sorta grew on the rest
of the industry. It hasn't been a fast mover for anything
other than aircraft. They're not hard to solder ESPECIALLY
if you're using modern coax with hi-temp insulation. I.e.
RG400 or equal.

Bob. This is the straight PUSH/PULL that I said that I already have. If I now connect a right angle adapter to it, its too long to fit into my panel. I need a 90 degree version of the 9-30-10. Then I can slide my radio into place, but only just. Go to the link below and see the fourth picture. If that tee connector was a PUSH/PULL male instead of a Twist on/off male it would work. |
Are you talking about THIS guy?

I can't imagine that this style of connection is any part of
an Icom product. The male end of this adapter is an RCA Audio
connector not often used at RF by anyone. My copy of the Icom
install manual has this image:
[img]cid:7.1.0.9.0.20091130140030.01e5c230(at)aeroelectric.com.1[/img]
Icom appears to have acquired a STRAIGHT version of the TED
connector with a BNC female termination on it. This would
nicely accommodate both aircraft and ground/portable ops
with any combination of BNC adapters and rubber-duck antennas.
The Icom supplied connector is not one I've seen before. TED
may even have built the thing. The TED connector I suggested
will, I believe, replace the BNC adapter described above
and allow you to attach the feedline coax directly
to the tray connector. Alternatively you can install a short
pigtail of RG400 on the tray connector with a cable female
on the other end so that you're transition to the world
of BNC connectors is preserved.

Bob. Your first "take" on my problem was correct. I just didn't realise that the opening on the side was for the coax to be inserted. Please see my post on the other thread and Thanks...Geoff

Radio Shack has a right angle, no solder, BNC connector at $4.99 P/N
278-126.
I don't know the quality, but it might be worth looking into.

wrong with 90 degree, or any other connector for that matter, that a

Agreed. There is merit to the notion of improving
reliability through the reduction in parts count . . .
but if you look at how a 90-degree connector is
fabricated, it STILL has a female socket into which
a pin crimped to the center conductor is mated before
the shield sleeve is crimped.
So the only parts reduction that can be realized by
going to an "on purpose" as opposed to "po'man's cluge"
is elimination of the second bayonet retention mechanism.
Combine this with a VERY long history of coax connectors
of ALL types. Properly installed, they are very low on
the list of common troubles in avionics systems.

The 90Deg replacement I mentioned previously is not a the common of
the shelf BNC 90deg adapter. It is a replacement for the TED
9-30-10. I have them in my Terra radio trays. I see that ICOM has a
straight version also, I understand they are used with several
manufacture's equipment like King. So IF you have the "TED 9-30-10",
the DBA-600 looks to be a nice clean application replacement for the
"TED 9-30-10" Look at my attachment it shows both connectors and you
can see it is not the common BNC 90deg adapter.

We got lost. The thread topic was asking about "90 degree,
BNC" connectors. The conversation stroked off down that
BNC river. The self-aligning, blind engagement connectors
like the TED 9-20-10 are not members of BNC family
of coaxial connectors. I don't think the tray
connectors have been named as a family . . .
Further, since the right angle, TED 9-20-10 attaches
right to the end of a piece of coax, it's not generally
referred to as an "adapter". It appears that the
straight-line product offered by ICOM is indeed
an adapter offering between-series mating of a
BNC male connector-on-coax with the blind-mating
connector at the back of the radio.

For my aircraft, I will never again use a 90 degree BNC connector. I will find another way to make the desired connection(s).

Adapters for coax connections come in hundreds of varieties.
Most adapters are used to make reliable connections between
different series. For example, the majority of my RF test
equipment comes with series N connectors while my shop
and product preference is for BNC or SMA connectors. Hence,
I almost never have an RF testing task that does not include
one or more adapters in the setup. A small but exemplar
selection of such devices can be seen here:
http://www.amphenolconnex.com/catalog/adapters.pdf
The only difference for the adapter Stan wrestled with
is that BOTH ends attach to the SAME connector series.
One could probably find somebody who makes a BNC/SMA
right angle, or TNC/N or UHF/BNC, etc. . . . The folks
at TED would be pleased to whip out any needed
configuration.
Stan's experience with the bad adapter is unfortunate
but fortunately very rare. I've replaced dozens of connectors
that were damaged or improperly assembled over the years
including some adapters. At the same time, I've worked
in facilities that had literally thousands of connectors
AND adapters of all styles that were never touched after
the initial installation except for servicing some piece
of equipment.
Stan has professed to being and "ignorant layman". I'll
suggest that now he has uniquely benefited from a memorable
if expensive lesson in his own classroom/shop. By
sharing his experience with us, he has armed us with
new ideas to explore when investigating poor performance
from some device that hooks to an antenna. Let us continue
to improve the return on investment for Stan's expense by
storing his experience away in our own gray-matter
archives.

Correct. It's a specialized connector.

I have soldered the connection in two places as shown.
When I solder the antenna connector on the other end.

Why are you using a soldered connector on this end?
Crimped is MUCH easier to install for reliable connector.

???? I'm not aware of any connector design (other than
the arcane UHF series) that calls for soldering to the
braid. If you use a connector designed for crimping
as above, then the braid attaches under the sleeve.
The only BNC connector I've ever soldered was this
style:

and soldering was to the center conductor only. The
shield gets captured under the shield clamp. Installation

I would not necessarily expect the no-signal noise
levels to change by simple adding or deleting an antenna
connection. You need to check first with a hand-held as
an external signal source. Then check on your local
ground services, approach control or ATC radar sector
frequency for traffic with other aircraft.
