ADS-B folded vertical - Interest check

[Anmer]

You better cut this coax to 10cm and continue with some Wi-Fi grade coaxial cable if nothing better.

I'm no expert on technical specs for antennae but after 9 years in this hobby, I know a good range when I see one.

I have a simple test for any antenna - make a polar diagram showing ranges at different altitudes.  These "magmounts" perform very well, depending on height and location.  And use quality, low loss coax for any long runs though I've never needed a run in excess of 10 metres.

What's "WiFi grade" coax?

By the way, what is the distance you have with the indor antenna?

edit:

The widely used coaxial cable among the Wi-FI users (because it is cheap) is LMR-400.
Compare the loss of the RG-174 and the LMR-400:

Up to 250 NM if I place it high up in my loft.
