What are swr's

The SWR meter or VSWR meter measures the standing wave ratio in a transmission line. The meter can be used to indicate the degree of mismatch between a transmission line and its load, or evaluate the effectiveness of impedance matching efforts.

It is a way of tuning the aerial length to be correct to the radio.

Cbradio and mobile operation

One of the few things i come across relating to the 11mtr band is operators setting vswr on low ground which will can totally give false readings sometimes .The best method while matching your antenna to your rig ,is to go to the highest peak possible ,Mountain etc and do all your settings from there you will be suprised the difference and outcome of this method .one instance ,ever set your base antenna on a we say a 10ft mast get a 1.1 match and then rise it 40ft suddenly the readings have risen to 2 or even 3 for that matter so if you take my advise you will allways have a low vswr hence better performance and long lasting communication from your rig ,note iff your vswr is high you can after prolonged use do damage to the final transistors so save yourself time and money and set as i have discribed

Remote controls will not work after smart meter installed by Central Maine Power

Power meter install is same as having a momentary power outage as meter is pulled from socket (like pulling extension cord out of outlet) and then new meter is 'stabbed' or pushed back into place.

I'm not sure if remote can flip off and need to be reset without knowing exactly what the remote operates, and the brand and model number of remote so I can look up possible instruction manual.

If you have a manual, then read about 'reset.'

Please add a comment with specific details for best answer.

A VSWR meter is your best bet. They are cheap for cb's . If the antenna is badly mismatched you will get an antenna warning lamp on. If the antenna has a tuning coil you will see usually continuity to ground from the whip. Use the vswr meter on the radio. Set to calibrate first, transmit on channel twenty while rotating the swr cal knob. set needle on orange triangle at top right of scale. Select VSWR mode and transmit. needle should move up slightly if antenna is tuned correctly. Try chaneel 1 and 40 with same procedure. You can tell if antenna is tuned more toward the high or low frequency by how high the needle is on the scale. The higher the reading the worse the match is. If there is always a high scale reading then try another antenna that you know works.Watch for flattened/damaged/water in between braid and jacket or corrosion on coax as this will change the coax impedance drastically

I have a midland 1001z, with a Cobra HGA1000 18 1/2 mag mount antenna cb antenna, obtaining power through a plug into the accessory outlet (connected correctly) and run a braided wire from metal under the...

Hi Harry, I just got your note - sorry that you've been waiting 3 days. Your Midland is the traditional 40 ch 27Mhz CB - unlike the "new CB" that is really the 460Mhz FRS system. The Antenna should work as it too, is for the 27Mhz CB system. You seem to have the power run correctly as the radio does power up and visually works.

The problem could be one of several things. First, adjust the volume to about 1/4 and check the position of the CB/PA switch. It should be set to CB. If set to PA, the mic audio is sent to a speaker that would be connected to the PA jack on the back of the radio. Once the switch is set to CB, you ought to hear static from the radio's internal speaker. If you do not, rotate the squelch counter clockwise until you do - and readjust the volume to your liking. Rotate the squelch clockwise just until the static is silenced. Tune other channels for activity. Ch 19 is popular if you're near a highway, otherwise try them all. Stop on a channel with stronger activity - as you'll have the best chances of contacting this type of station (it is presumed to be closer to you). Key your mic to attempt contact between transmissions (the meter should indicate 3 or 4 for up to 3 or 4 watts output power when transmitting - if it does not, you should check your antenna and coax cable for damage and proper VSWR). The other station can not hear you while they are talking.

If they do not respond, try another channel and begin again. If you are unable to get a response, there may be an issue with your antenna or coax as mentioned above. Make sure that your coax cable is not crushed, pinched or cut. Replace and reroute any portion of the cable that is. Use the correct connectors or approved coaxial splicing devices. Twisting wires and braids together and wrapping with electrical tape is not the way to do it.

You can read some excellent info about VSWR from Firestick - a premium antenna manufacturer - here. I hope this helped and again, sorry for the delay. Please rate my reply - thanks!

I can only hear people close to me on my CB, what could be the problem?

Sounds like a problem with the antenna system. Test with a VSWR meter (also called a "standing-wave" meter) if the antenna system is OK. Also, what happens if you connect a different CB radio to the antenna? This will tell you if the problem is with the antenna or with the CB radio.

Turns on ok but when I key to TX there is on forward or reflected signal I have conected it to a vswr meter wiyh a dumby load fr the antena

Sometimes dummy loads will show a more
then hi reflected power ( that's power that is
comming back to the radio ) try it on a ant.
an see what you get.The type meter I use only
shows reflected power and not SWR.
Maybe this will help
