If your swr is higher on 1 then on 40 then your antenna is electrically short and you have to lenghten the antenna.If it is higher on 40 then on 1 then it is long and you have to shorten it. If you have to make it longer then you may have to add a quick disconnect or a coiled spring to make it longer. To make it shorter all you have to do is trim a 1/4 in at a time off the antenna whip but you must keep checking the match until it gets down below 1.5 .
SOURCE: The whip on my antenna came loose.
considering the cost of a new one. repairing would be a good idea.
SOURCE: swr low on lower channels
Connect a standard mobile antenna to the set and see if you have normal tx / tx/ audio out...if this is all aok you have a problem with the antenna / antenna equipment / installation/
GOOD LUCK
SOURCE: Cant get SWR below 3.5
A ground wire will not replace the lack of ground plane. Try a different antenna altogether (possibly one with a magnet mount) and mount it on some metal surface like even the front hood and retest.
I am sure the problem you will find is with the lack of a proper ground plane.
SOURCE: transmitting and receiving
RF gain should be all the way up. Turn the squelch all the way down. Turn the ANL/NB to just ANL.
Turn the dynamic up at least 3/4.
Once you have confirm you can receive and transmit, then you can turn up the squelch up until white noise just stops.
Make sure you are on 19 by the highway. Key up and say break break one nine, can some one give me a radio check please.
you should get a response.
Your RF gain is how much you receive. the higher it is the more you receive. In normal operation there is no need for it ever to be less the all the way on.
Squelch is just to knock out fuzz, and if you only want to hear people close not far. A little less then half way is a basic setting.
the ANL switch is the automatic noise limiter. if you have interference from your vehicle, like engine noise, turning this on will quiet that. If it is extreme engine noise then switch it to NB, noise blanker. It is just a more intense setting.
your dynamic is how loud your audio is. if its low or all the way down, you will not transmit audio loud enough for people to hear. If its a stock radio and has not been tuned, if you turn it all the way up, that is fine.
SOURCE: my cobra 29 i can not set the swr on the antenna,new swr meter
then there may be prob with antenna system or radio has too low of dead key to operate the meter.
