KX2 mini-banana plug improvement

It would be nice if Elecraft offered a mini-banana plug for use with the
KX2 that would have a binding post or other device that would allow the
counterpoise to be attached without soldering the wire -- the binding post
to bnc connector is nice and the same binding post would be useful with the
mini-banana plug.

Re: KX2 mini-banana plug improvement

Not exactly what you're asking for, but for stackable, non-solder mini
banana plugs, try Pomona #2945s; you can get them from Mouser and other
places online. I use the Pomona #3296 mini binding post adapter for my wire
antennas, so mini-banana is my common connector. Biggest downside is that
the Pomona parts are pricey.

Re: KX2 mini-banana plug improvement

Bob,

If I understand your question corretly ---

But why? If you are using the BNC to binding post adapter, the ground
connection is to the same board PC ground plane as the ground connection
of the BNC to binding post adapter.

The use of the mini-banana plug is a convenience for those operating
pedestrian mobile and provides a connection for the trail wire that will
easily disconnect if the wire encounters a snag - protecting the KX2.
Do not make it anything other than that. If you can find a mini-banana
jack to binding post adapter, then it can be used instead of the
Elecraft supplied connector. You are welcome to query the web, but I do
not find any.

If your pedestrian mobile situation uses anything other than that
mini-banana jack, then you could could cause damage to the KX2 if the
wire encounters a snag.

If you can find a mini-banana jack to BNC adapter, then you can have
your wishes, then you will have your solution.

73,
Don W3FPR

Re: KX2 mini-banana plug improvement

I vaguely someone suggesting connecting a power
pole to a single mini banana plug via a short
lead. Then different counterpoise lengths can be
connected via the power pole, and will still pull
out from the banana socket if stepped on.

Seems like a good plan, and there would be other
ways to implement the same concept -- so dealing
with connecting to the mini banana plug need be
done only once.

Re: KX2 mini-banana plug improvement

Could these BNC adapters be used for it? No additional weight, no more
space required.

Re: KX2 mini-banana plug improvement

It says balun connector. Does that mean it is like the old F to twin lead connectors that had a balun internally. If so I don’t think it would do what you want it to.

Hi,

Don't try to transmit through any of those, even QRP! They are for receive only such as FM and TV. I also doubt that most of them are effective below 50MHz.
