Tram® Glass Mount All-band Scanner Antenna

I put this on a 12 jetta tdi back window, i scraped off an inch of the defroster grid lines to have a perfect coupling, then reconnected and rerouted the circuit over the top of the coupling box inside with a conductive pen using a straight edge. Seems to be working terrific! All local stuff within 5 miles is full five bars on the digital readout. P. S. In case anybodys going crazy trying to find out, the 12 vw jetta tdi, does NOT have passivated glass. Goidluck.
