Is this the actual design and dimension of the F-dipole of this antenna? May I know why two different Coax (RG-638 and RG-213 Coax) is used? Is this for impedance matching purposes?

I will post soon, but i think the manufacturer tested the antenna wth the 10 meter RG58 cable in roll (as shown on the photo in the first post), which means ghe manufacturer has wrong steps in testing the antenna.

Here are the s-paramter for the folded dipole itself only. It seem like having 4 different working frequency. So bad 2.6Ghz is missing which is a common LTE frequency
