d'avoir répondu à mon post, c'est que l'on peut avoir un circuit explicatif qui me permettra d'implémenter mon antenne avec une impédance coaxiale de 75 ohms.
Merci

Hello Admin, 

I would like use this antenna for 4G LTE (1800 Mhz) witha 75ohm cable. If I want to add the 2nd feed, should I put it at 120° as always? 

Thank you

Hello Admin, 

Can I use this antenna with a parabolic dish for 4G LTE (1800Mhz)? Is it the best solution or do you have other improvements? 

Thank you
