SOURCE: instructions for a swr meter/cb radio

An SWR meter is used to see how well your antenna is matched to your transmitter output, just like using the correct speakers with an amplifier.

There are usually two readings. FORWARD and REFLECT
or FWD and REFL

Firstly, make sure the antenna selector is in the correct position and set for the antenna you are using.

Next, switch your meter to FWD (FORWARD). Switch your transmitter to low power and press the microphone key.

Next, adjust the CAL knob for the maximum power reading, but not so far that the meter exceeds maximum!

Keep the microphone key pressed and switch to REFL (REFLECT). If your antenna is matched, the meter should now give a low reading. If the reading is very high, you must match your antenna by making adjustments or by using a matching unit.

A poor match will mean a poor signal. A very poor match can damage your transmitter and cause interference.

When you have a good FORWARD reading and a low REFLECT reading, your system will be reasonably matched and you can then use higher power. Remember that you will need to reduce the CAL knob to a lower setting when running high power.

Adjusted mag mount antenna w/a swr meter. When checked it w/the meter on the '06 uniden pc78 elite, ch 40 was a lot higher. Which is correct ?


The coax jumpers between the meter and the radio can change the SWR a little bit. It is very unlikely the the antenna can be that low on 1 and 40. Set it for the lowest on 20 via the radio and as long as you are under a 2 on 1 and 40 then it should be OK.

3300hp how many watts output, what swr/ power meter should be used


That style will get about 60w PEAK.. on older styles.. the newer Mosfets will do about 30-40ish..

Meters, are preference.. most are just RMS styles. and you wont see the Peak reading which is fine. there are alot of meters and brands.. Bird, Dosy, MFJ, Siltronix. they all have pros / cons.

if just want simple workman makes some lower end styles. also para dynamics..

there are some MFJ and other brands that have cross needles that show both power and swr at same time. but they will start in the $60ish range and go up from there.

No instructions were included in package.


swr meter operation as follows go to channel 1 flip the switch on the swr to cal key the mic adjust the needle on the swr meter to the dash mark at the far right of the meter use the dial on the meter to adjust then unkey your mic and flip your switch to swr re key the mic you should not be higher than 1.5 on any channel repeat the proccess on 20 and chan 40 if the swr is higher on 40 than 1 lower the antenna or trim it but only 1/4 inch at a time.

Swr meter not moving


follow these steps to adjust the
standing wave ratio(SWR).
1. Turn on the CB.
2. Set S/RF/SWR/CAL to CAL.
3. Key the Mic and rotate SWR CAL so the meter points
to CAL.
4. Unkey Mic.
5. Set S/RF/SWR/CAL to SWR.
6. Key Mic again and note the actual measurement on
the SWR scale. Refer to the following table to interpret
the reading.

1:1 - 1.5 Great
1.5 - 2:1 OK
2:1 - 3:1 Not So Good
Higher than 3.1:1 Terrible

Need instructions on how to swr my cobra 29 ltd bluetooth


You insert an SWR meter in the antenna line, usually one end goes into the Antenna OUT socket, and the Antenna plugs into the SWR meter, you then tune you antenna coupler, inductor, & final PA, in the final stage, until you achieve a 1:1 SWR reading, this is however quite hard to achieve, so simply tune for the closest 1:1 SWR that you can achieve.

No cb signals from new units


Good power supplies and good quality coax is important also.
Check SWR too.

Get a External SWR meter:
with the switch in FWD position, key radio and use the CAL knob to set the meter so the needle is just touching the end of the red area on the right-hand side of the meter.
Once calibrated, unkey and switch the switch to REF and key up again. The lower the reading, the better. Check the SWR on channel 1 and channel 40. If the SWR is Higher on 40, the antenna needs to be shorter.. if its higher on 1, then the antenna needs to be longer. Assuming the antenna is adjustable, of course.

1) push the button marked S/RF / SWR / CAL to CAL

2) Hold in the button on the mic

3) Turn the SWR CAL knob until the needle is over set to the far right of the meter

4) flick the switch (in step 1) to SWR

Your SWR reading will be displayed. The more to the left the better..

Matching c b antenna with c b radio


here is some information that will help you test SWR with an inline watt meter. To get proper results you need to use an inline watt meter. Here is a really good site you can go to for help www.cbradiotalk.com

Equipment needed: SWR meter, short jumper coax 3 foot.
midland.jpgProcedure: The SWR meter needs to be placed in line between the antenna and the CB. Connect the antenna (normally connected to the back of the CB ) to the connector marked "Antenna" or "Ant" on your SWR Meter. Connect one end of the short jumper coax to the "transmit" or "Xmit" on the SWR meter. Connect the other end of your jumper coax to the CB.
Assuming you have a standard SWR meter the switches should read as follows: REF or SWR, FWD, and there should be a slide switch marked "set" or "Adjust". If different consult your meter's owners manual.
With the radio on the lowest channel (1 on CB) and the SWR meters switch in the Forward (FWD) position, depress the transmit switch (key up) located on the microphone. While holding the unit in this transmit mode, adjust the meter needle to the set position using the Set or Adjust knob on the meter. As soon as the needle is in alignment with the corresponding mark on the meter face, flip the switch to the Reference (REF) position. The meter is now showing your SWR on channel one. Note the value and quickly release the microphone switch. Record this reading.
Repeat the previous step on channels 19 and 40.
How to read your results: If SWR on channels 1, 19 & 40 is below 2.0, your radio can be operated safely.
If SWR on all channels is above 2.0 but not in the "red zone" (normally over 3.0), you may be experiencing coaxial cable reaction (bad quality, wrong length, etc.), insufficient ground plane, or have an ungrounded antenna mount.
If SWR is in the "red zone" on all channels, you probably have an electrical short in your coax connectors, or your mounting stud was installed incorrectly and is shorted. Do not operate your radio until the problem is found, serious damage can occur to your radio.
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.
