Frank, You are correct that more ports results in more loss - Mini-Circuits has nice data sheets for their products. The first one has about 6.8 dB loss at GPS frequencies. - a "perfect" splitter would have 6.0 dB
That last one is actually a SIX way splitter, two of the outputs have blue caps on them. A little under 9dB loss at GPS frequencies. https://www.minicircuits.com/pdfs/ZN4PD1-63HP-S+.pdf https://www.minicircuits.com/pdfs/ZB6PD-2+.pdf -Joe KM1P ________________________________________ From: time-nuts <[email protected]> on behalf of Frank O'Donnell <[email protected]> Sent: Wednesday, April 29, 2020 10:06 PM To: [email protected] Subject: Re: [time-nuts] GPS antenna splitter recommendation?

What I'm looking for is one that will accommodate (specifically) three or four ports. Of the remaining two on the list, this one: > https://www.ebay.com/itm/Mini-Circuits-ZN4PD1-63W-S-RF-Power-Splitter-250-6000MHz-Qty-Available-GOOD/133387795141?hash=item1f0e883ac5:g:tdoAAOSwAbxel2o~ > > <https://www.ebay.com/itm/Mini-Circuits-ZN4PD1-63W-S-RF-Power-Splitter-250-6000MHz-Qty-Available-GOOD/133387795141?hash=item1f0e883ac5:g:tdoAAOSwAbxel2o~> has five outputs and costs $50. Probably usable, though I was wondering if going with additional output ports could increase possible loss? And also, the price isn't a show-stopper but is a little high for what I was hoping for. The other one: > https://www.ebay.com/itm/New-Mini-Circuits-ZB6PD-2-S-800-2000-MHz-Power-Splitter/114155096838?hash=item1a942c8b06:g:jNIAAOSwedNedT92 > > <https://www.ebay.com/itm/New-Mini-Circuits-ZB6PD-2-S-800-2000-MHz-Power-Splitter/114155096838?hash=item1a942c8b06:g:jNIAAOSwedNedT92> isn't entirely clear to me. The text says it's a three-port, but I count four visible connectors that look like output ports, and two more that might be hiding under caps. This one goes for $19.90. Given all of that, do either of these two seem like the optimal way to go if I want to plug in three or four GPSDO's?
