How do you tune the antenna on a Cobra 29 LTD Classic?
Tuning your antenna using the Cobra® 29 LTD Classic:
Press and hold mic button. Adjust the SWR CAL dial until meter swings right and sits directly under “CAL” on the meter. Keeping the mic button depressed, switch the SWR toggle back to SWR and write down the SWR reading on the meter.
How do you adjust a Cobra 29 LTD?
Starting from the left the first controls are the volume and squats knobs. The volume controls how loudly you’ll hear people over the speaker.
How do you check the SWR on a Cobra 29?
Adjust the calibration control to the Cal mark on the meter. And then click the switch to read SWR. And you can see that on the top scale.
What does ANL stand for on a CB radio?
Automatic Noise Limiter
If you notice something missing or incorrect, just let us know! ANL- Automatic Noise Limiter – A noise limiter clips an audio signal to reduce the amplitude of impulse noise. It prevents the waveform from exceeding a certain level. Bluetooth – This feature has been added to just a couple of Cobra CB radios.
What does NB ANL mean on a CB radio?
What is the NB/ANL switch for? The Noise Blanker and Automatic Noise Limiter are used to reduce the amount of unwanted static, or interference you can get from many sources. Specifically these functions are mostly used for unwanted ignition noise, power lines, inverters, etc.
Should my CB be on SWR or S RF?
In the S/RF position the meter will show transmit power and receive signal strength. The CAL and SWR positions are only for checking the SWR of the antenna. Recommended Setting: The S/RF position.
Can high SWR damage a radio?
IMPORTANT NOTE: Radio damage will only occur when you’re TRANSMITTING from an antenna with high SWR readings.
Can SWR be too low?
An SWR too low over the whole band (1:1 for all 40 channels) can indicate a low efficiency antenna or lossy component. Safe operation of your CB should be with an SWR of 2:1 or less. Most people would prefer to be 1.5:1 or less.
Is CB Channel 9 still monitored?
Channel 9 is the universal CB emergency channel. In most areas, it is monitored by local law enforcement at all times, so please keep random chatter off this channel.
What CB channel is used most?
Channel 19 is the most commonly-used channel by truck drivers on highways, to the point that some radios even have a dedicated button to bring up channel 19 instantly. In many areas of the US, other channels have been used in the past for similar purposes including 10, 17, and 21.
What settings should my Cobra CB be at?
Recommended Setting: The 12:00 position. S/RF, SWR, CAL SWITCH – The normal operating position is the S/RF position. In the S/RF position the meter will show transmit power and receive signal strength. The CAL and SWR positions are only for checking the SWR of the antenna.
What should SWR be on CB?
SWR 1.0-1.5: The ideal range! If your SWR is under 1.5, you’re in great shape. If you’re at 1.5 and really, really want to drop down to closer to 1 it’s likely possible to do with addition tuning, different equipment or a different mounting location.
What SWR is too high?
If the SWR on channel 40 is higher than that on channel 1, your antenna is too long. If the SWR on channel 1 is higher than that on channel 40, your antenna is too short.
Can a pinched coax cause high SWR?
Damaged coaxial cable is a big reason behind high SWR readings. A coax can get twisted, shorted, or pinched while routing through the vehicle. It might come damaged when buying from the market. Hence it is essential to check your coax cable thoroughly before purchasing.
Does the length of coax cable affect SWR?
If you use a length that is shorter or longer, you might risk having trouble achieving good SWR readings. Properly store any excess coax in a figure 8, about one foot in length, and bound in the middle- it should look like a long, skinny 8.
Is an SWR of 2 OK?
SWR 2.0 – 2.4: While not good, this likely won’t damage your radio with casual use. However, you should definitely try to improve it if you can. SWR in this range is usually caused by a poor antenna mounting location and/or a poor choice of equipment for your specific vehicle.
Does coax length affect SWR?
Coaxial Cable Length Does Not Change Antenna SWR.
What is the most active CB channel?
What CB channel do most truckers use?
CB Radio Channels
Channels 17 and 19 are the two channels most commonly used by truckers; in some areas, those on north- and southbound roads use channel 19, while those on east- and westbound roads communicate on channel 17.
Is CB channel 9 still monitored?
What CB channel do truckers run on?
Can CB SWR be too low?
How do I bring a SWR down?
If your antenna is mounted down low on the vehicle, like on the bumper or behind a pickup truck’s cab, the signal can bounce back to the antenna, causing a high SWR. To alleviate this, keep at least the top 12 inches of the antenna above the roof line, and position the antenna as high as possible on the vehicle.
Is it OK to coil coaxial cable?
There’s nothing inherently wrong with “looping up” extra coaxial cable. In fact, a neatly wound coil of coax can function as an air-core choke balun (“ugly balun”) which is useful for some antenna systems when located at the feed point of the antenna.
