Nolec Antenne and acars

Hi to all, someone with Nolec Antenne for adsb dvbt stick?
i have bought this antenne … UTF8&psc=1

because i have a third dvbt stick and i use them now for acars receiver, i have tested change this antenne with original dvbt stick antenne and recepcion is realy poor, but for acars messages is ok.

Another question is, i have set in acarsdeco2 url path for sillhouetes but silhouetes dont hapear , i have a folder on my web site with all silhouetes unziped, what is wrong here? just click on live acars button and you can see all messages without silhouetes, silhouetes folder is on the same website, maybe something wrong with write read permissions?

Thanks in advanced
