Thread: C27 SWR tuning

  1. #1

    Default C27 SWR tuning

    I have an antennex c27 with a trunk lip mount in my car. I trying to tune the swr in it but I'm not really sure what to do with the readings. I lost the little paper that said how to tune the antenna, and im not sure if I have to.

    Here are the readings I got:
    CH1: 3.1
    CH19: 2.8
    CH 40: 2.6

    Do a Google search on SWR. Your antenna needs to be raised.

    If SWR on the lowest channel is higher than it is on the highest channel, your antenna system appears to be electrically short. Your antenna length may need to be increased.

    If the SWR on channel 40 is greater than that on channel 1, your antenna is considered to be "LONG" and reduction of physical height and/or conductor length will correct this situation.
