If you only need two outlets you can just do a passive splitter,
you need a tiny capacitor in series with the center wire on one of them
and a resister to GND to fool the antenna-current monitoring circuit.

Hi Magnus:

I use satellite splitters and amps for GPS, see:

Have Fun,

I picked up an HP 58516A (four-port) on ebay last year, very cheaply. I
didn't need four ports, but the price was right.

Magnus, you probably already know this, but just in case you don't, I'll
mention it. Those HP splitters come in two varieties. On one, the 5VDC is
fed into port 1. On the other variety, the 5VDC goes to a separate SMC
connector. Mine came with the SMC connector (of course) and I had trouble
finding the mating connector.

Magnus,

Over the years I've picked up all mine on eBay; good
ones by HP/Agilent, or Symmetricom. Ignore the high
fixed-priced sellers; if you're patient you can get them
for as little as $10 to $20 per port. Many of these are
still new (telecom surplus). Search by P/N:

58512A (2-port)
58516A (4-port)
58517A (8-port)

58535A (2-port)
58536A (4-port)

58504A antenna (puck)
58532A antenna (cone)

Actually, it might be if you're not too concerned about phase noise.  I've
used video distribution DAs in the past with good results, but they're
limited to locking purposes only.

I gotta say this about eBay, if you wait long enough you
will get what you want.

Specifically, I bought 2, 8-way splitters for $100.00 each from The
Tucker store.
Both had the power connector which was a SMC connector (I believe).
Takes 5Volts to make it run even though the markings indicate that
the power could also come from port 1.

So you think that having 16 devices might be too much? Well guess again,
I am on the lookout for another.

There is one guy selling a 2-way and a 4 way for $$$$$.

My advice: wait a bit.

Can't wait? a passive splitter will do fine.

Make sure it passes DC. Your antenna will need it.
Pass the DC from one port and block it from all others.

Regards,

Tom,

I was bidding on a 58517A but since Ebay isn't a good action-house, there is no
real chance to raise bids.

Cheers,
Magnus

A 50nF Cap should do just fine.
Little smaller/bigger probably ok as well.

Size? A small ceramic should be fine.
After all we are not expecting KW.

Hmmm... I wonder what the power output of a GPS sat is?
Is that classified? Even if it is, if I know it's height
I can probably figure it out. Estimate at least.

Sorry, just thinking out loud.

Here's an eBay search I built from Toms list.
(58512A,58516A,58517A,58535A,58536A,58504A,58532A) ("HP", "AGILENT",
"HP/AGILENT", "HEWLETT PACKARD", "Symmetricom")

I researched that 58535A Glenn mentioned; they've been trying to sell it since
May with no takers.

I was thinking of putting up a FOL-100 fiber optic antenna link, with fiber and
connector.

GPS Networking and GPS Source are also makers of good ones. Though they
are not as usual at Ebay and harder to search for.
