Well your question can be taken two different ways, 1) how does it and 2) how well does it do?N467RX said:Can anyone tell me how do the glass mount antennas transmit the signal thru the glass?
Rather than start a new thread, I would like to take this discussion out a little farther.N467RX said:Can anyone tell me how do the glass mount antennas transmit the signal thru the glass?
The frequency range is determine by the whip, not the coupler. The coupler merely provides a match to the 50 ohm cable feeding the antenna. I've seen some that are adjustable, which just allows the installer to match for best vswr. Tuning for frequency would occur outside at the whip. If you try to go to a different band, it's likely that the coupler portion would not be adequate to provide a 50 ohm match and, depending on what they're doing, could add quite a bit of attenuation.af5rn said:Are you saying that the coupler is tuneable to determine frequency range or mid-frequency? Or are you saying it is factory tuned and not tuneable by the user? Is the same one in every antenna, or is it a different one in each antenna depending upon the band?
