In my opinion, and if i had a car like that. Spend the money. I would place a transponder head in the center grill and two transponder heads in both of the outside grills for a total of three upfront.

You pick the jammer blinder although larger footprint, lidatek smaller cross section smaller footprint etc.

To me its has to perform and look good at the same time.

take care sure you will make a good informed decision,
