I bought this 16.5 cm antenna with 3m cable and SMA as a starter with the FlightAware Pro Plus stick as I wasn´t sure where I´d exactly mount things. (currently right under the roof-top)
NooElec quoting the same 3dBi gain for their dedicated 1090MHz 8.5cm mini antenna I took the plunge, cuz I thought it must be better when I use it same position without a cable / directly on the receiver.
Reality: When I get a dozen planes and up to 400km coverage with the prior antenna, I don´t get a single one with the NooElec. <aarrrggghhh>
Please explain! Thanks
