ADS-B Antenna Splitter

[BVE16]

Hi guys. Anyone know a good antenna splitter . Want to use two boxes on one aerial . Saw a few on eBay but seem suited for satellite. Also worried about any loss that might happen.

You're right about satellite cable splitters.

I have an RF Systems SP3.  No perceivable loss of signal but it's expensive:

Next I found a Mini-Circuits one on ebay.  It's a four way device (they come smaller and bigger) that was shipped from the US.  Again no perceivable loss of signal using one antenna to feed 4 receivers.

Mine was a Mini-Circuits ZB4PD1-2000 Power Splitter/Combiner, 2000 MHz.  Total cost US$40, including shipping and tax.

Both splitters are still in use and have been for many years.

If you go the Mini-Circuits route, make sure it covers 1090MHz and has appropriate connectors.

This one may be OK.  There are others listed:

Even better, here's one like mine:

Thanks Anmer. Got the mini circuits one and a couple of decent cables from RS components. Will see how it goes when i get it. Looks like the RF systems are no longer made or sold which is a pity.

  I needa VHF one can you recommend some?
I need them with many Ports for my VHF Antenna when you understand what I mean.

Maybe a Mini-Circuits one that covers the VHF frequency range?

Thanks Rob.  Useful links.

As expected, expensive.  Which is why a pre-loved Mini-Circuits might be a better option

What do you think of these?

MCL MINI-CIRCUITS ZX10-2-20 .2-2 GHz SPLITTER FOR VHF UHF APPLICATIONS

This is the ebay item couldn't get the link to work.

[Anmer]

The ebay listing doesn't state the frequency range or the connector type.

Maybe check the model on the Mini-Circuits website?

Ideally you need SMA connections and a frequency range that covers 1090MHz

For example, this looks suitable:

Thanks for the reply.

Zooming in to the photo they all look like sma connectors and the label says 0.2 2Ghz, and just looking at the data sheet confirms the frequency range.
Will double check with the seller.

No SMA connectors but I got good results with the Andrew S-2-TCPUSE-H-N High Power Splitter. Used it to feed my ADS-B signal to my SBS-1 and Airspy-mini.

[G4UMW]

BNC or N-type connectors are acceptable at the frequencies involved.

[Anmer]

BNC or N-type connectors are acceptable at the frequencies involved.

But if the receiver and/or coax cable are SMA, adapters will be required.

[G4UMW]

True, but BNCs and N-types are easier to fit to thicker coax.

[Anmer]

True, but BNCs and N-types are easier to fit to thicker coax.

Which is why I prefer 6mm low loss coax.
