I found this a couple of days ago,

And it got me thinking,

I have a need for a few outside aerials, covering

170-230 MHz
88-108 MHz
1090 MHz
131 MHz
165 MHz

What's the best way to combine all inputs to 1 drop cable, and then splitting the signal back out to my dongles/radios.

@John @scopus @Llew @Vipersan or anyone else have any ideas please?

Thanks.
 
You would require a diplex/ triplex outlet plate.
Also note, UHF port is not LTE filtered.
 
Can't think of any combiner that would handle all of those bands
 
I wondered if it is possible, and how I would go about it.

I can live without the fm and dab in the same line.

Can such a thing be made?

Yes, but it isn't currently.
Not too difficult, though. Just a bunch of R/F filters. Quality depends on price of components, and focus of designer.
Still, the alternative of pulling separate cables will yield better performance...
 
A Global loftbox will combine DAB/UHF/FM and Sat.
Satellite will only be available on the Lounge output, and a diplexer wall plate is needed here. DAB/UHF and FM would be available at all the other outputs, but you would need diplexer plates if you wanted anything other than UHF at outputs 1-4 or 1-8 depending on which loftbox you wanted.
 
I am really trying to combine an aerial for

1090mhz & 131mhz & 165mhz and if I was lucky enough to have a spare input, so I can run the signal to my dongles.

So I am able to decode acars and ads-b and a voice channel active in my area.

Not sure about that, in my time I've seen many an 'electrician' create something of art under the floorboards, in walls, under the eaves etc. Sometimes under insulation tape, sometimes with chocolate blocks.

Just get one of these antennas, it covers a lot of bands, and will transmit in some.

Evan will be over in a few minutes to rearrange your teeth and sock drawer.
 
What teeth??? I keep my dentures in a glass of scotch at night, makes for a tasty morning coffee.

But if someone needs some teeth, the local cow town bar sweeps up the leftover teeth and eyeballs every Sunday morning, I'm sure someone could find some that would match.

As to the socks, bring a clothes pin as they are all in the wash.

As Terry said, you'll be better off with a discone e.g. Base Discone Antennas - Scanning Receiving and SDR antenna This looks interesting: antenna
If you are trying to combine several high gain antennas that's a different problem and you'll need a custom multiplexer as ST1 proposes.

Try web searches for discone & biconical for some home made ones. Both are omni. If you want wide band directional, look at log periodics.

The split at the RX end is more difficult. You could put a wide band, high dynamic range, pre-amp at the antenna then use a wide band splitter at the RX end. The pre-amp needs enough gain to overcome the feeder and splitter loss but not so much that it, or anything else, overloads.
 
BZZZZZZTTT it's stopped.......
 
Now if you had some room.........One of these hummers would do the job.
