Back in 2008 I bought a Kuhne 1090 LNA and briefly fitted it at the mast top way back when I was using the original RadarBox hardware device.
Unfortunately it had the opposite effect of by actually reducing the amount of aircraft that I could see in MyFlights instead of the expected increase!
This I put down to the boosted signal overloading the front end of the RadarBox and so I reverted to feeding it from my external Watson Radar Extender via 5m of Westflex 103 directly into the RadarBox through an N-SMA adaptor.
Fast forward 12 years and I am now using a Raspberry Pi 4B and AIrNav FlightStick with the original antenna/cable and although I am pleased with my current Max Range of 295Nm and Avg Range of 219Nm located 150m ASL part of me wonders what the effect of the Kuhne might have these days when feeding this particular setup?
It could go one of two ways as I see it;
As above where the boosted signal swamps the receivers front end as I also believe the FlightStick has its own LNA & filter built-in doesn’t it?
If the receiver has become hardened through the years by better design, components etc. the extra signal strength could achieve its intended purpose by increasing the range and by definition the amount of aircraft I can see.
Does anybody have any experience or indeed theories about what adding the Kuhne might bring to the party?
I see from the Kuhne website that the current model is now called -2 so guessing that’s been redesigned/improved since my day although I don’t know what the differences might be?
Thanks & kind regards,
