antenna range improving ..?


#1

Hello

any ideas / suggestions to improve my antenna range am using FlightAware’s own " 1090MHz ADS-B Antenna - 66cm / 26in " , i don’t think am getting good results my antenna is fairly high ,
here is my stats page flightaware.com/adsb/stats/user/ALITALLA

Check your terrain limits here:

follow the instructions from “8 ): ADD TERRAIN LIMIT RINGS”

this will give you a guide of your possible range limits due to land mass/elevation etc.

Also are you using any filters? what Coax are you using? is the antenna outside?

Also, have reasonable expectations… You can’t see what is not there. How are you stacking up with the closest other tracker locations?


#4

am feeding data using FlightAware’s stock equipment’s , am not using any filter , my antenna cable is a 15 meter Cable N (male) - SMA (male)

If using 15m of cable then I can only suggest it is good LMR400 or equivalent cable.

also have a read of this:

Your coverage graph looks good with a fair amount of positions reported over 200 miles.
It seems that the vast majority of the flights are detected over Spain with practically nothing from the west or south, maybe your view is blocked that way (Atlas mountains)

I keep tweaking things in my setup, I rarely ever gain much additional range but tend to improve hits in existing range, seems to be a point where the only thing you can do is move obstacles (those mountains will be challenging to get out of the way!) or get more height.

There is a guy near me who always sits at top of charts on messages and aircraft, turns out his antenna is in a rural area on top of a hill with 360-degree views.
