[Zhu_000 1]

 

hi there im new here and i know nothing about antennas,

i have few antennas that i can choose on the picture,

if you guys can give me advice on which one i should choose for maximum dbi gain paired with 45 cm dish for 2100-24xx mhz based on your experience i would be grateful.

i believe this is common antenna design right? but i really dont know anything about the frequency, so i dont know which one is correct.

thanks.

note : 75 ohm coax (RG6/U)

it would be GREAT to put a VNA there on ALL 5 and check HOW they behave ...tho
