Do you need 75 Ohm? Surely it should be 50 Ohm for 1090 MHz?

What are you connecting?  From, what to what?

Ah, gottit.  Sorry I misunderstood.

Where is the antenna located in relation to the SBS?  It sounds like you want to connect the SBS directly to the antenna?  Most antenna coax comes with an N-type for the antenna and SMA for the receiver.  I use short patch leads to connect receivers to the Mini-Circuits splitter.  They're 50cm long, bought off ebay.

There was no impedance quoted and for that length I don't think it matters.

Hi

current way is aerial---mast amp---earth box---indoor connection block-----bias-t-----receiver

this is the "earth box" in the box is an diamond sp1000 and sp3000 lightning arrestors with a claimed insertion lost of less than 0.3db.

box and fittings are ip67 rated so it seals the cable access though my wall



the rg58u is an now unused power feed to scanner amp then the RFC400 is airband then 1090.

the plug style on my indoor connection blocks are n type females

so i am looking to take out the now un-used bias-t that is currently "BNC to sma" and connect directly to the indoor block thats needs "male n type to sma"
IE: aerial----earth box---indoor connection block-----receiver.

i am using right now a n type to BNC adapter but in VRS my receiver stats have gone werid thinking it a bad adapter

going though bias-t


using BNC adapter

So you need a <1 metre patch lead with N-type male one end and male SMA the other?
