WTB: HF Multicoupler/Antenna Splitter
 

I'm looking for a HF (500Khz to 50MHz or so) multicoupler/ antenna-splitter
that would allow mulipler receivers to use the same antenna with little or
no signal loss or interaction.

Ideally, this unit would have SO-239 connectors. Number of outputs would be
4 at a minimum, more is better. Will consider active or passive units.

Thanks

There's a kit on Ebay...looks good.

I found it by searching under "HF Receiver"

Universal-Radio.com lists several units too

You might want to check this out:

Though I don't think any have SO-239's, they work very well.

I use the MCA104 here, which is quite similar to the MCA104M.

Beware of the sticker shock though, as prices have gone up.

Avoid anything by Stridsberg - overpriced!

Try: http://www.arraysolutions.com/Products/ice/

Not only will it meet or exceed specs of anything Stridsberg builds for a
LOT less money, ICE will custom install the connectors of your choice at no
extra charge. I use ICE active multicouplers for my guard receivers, and am
very happy with all of the many products I have purchased there.

Yes, Stridsberg is indeed expensive. I may order up one of the ICE units and
test it out.

I was fortunate enough to get my MCA104 on eBay a number of years ago for $60.

Do you use the supplied power supply or do you use something else for
the +12V DC?

The one I have that I purchased on eBay did not come with a power supply. I
currently use a wall-wart.

Here is a website with a good multicoupler, low noise and well built.

Mini-circuits has them.

4-way passive:

8-way passive:

On HF, noise is the limiting factor, so if you still have the S-meter
moving above where it is when nothing is connected when you insert the
8-way splitter, you haven't lost much. (Yes, Nf, but is that really
relevent here?)

Don't know how to read the charts? Call Mini-Circuits -- they happily
do quantity 1 orders and have been helpful when I've dealt with them.

(Mini-circuits modules are what you find inside Stridsberg splitters.
I don't know about ICE, but they are a reputable company, so you
should get good quality whatever they do.)
