How do you set the SWR on a Cobra 29 LX?
On the radio, press the SWR/CAL button until the display says “CAL”:
- While pressing the transmit button on the microphone, turn the SWR CAL knob until the meter reads to the CAL mark. (
- Release the transmit button, then push the SWR/CAL button until the display says “SWR”.
- What is SWR?
How far will a 4 watt CB transmit?
Transmitter power is limited to 4 watts in the US and the EU. CB radios have a range of about 3 miles (4.8 km) to 20 miles (32 km) depending on terrain, for line of sight communication; however, various radio propagation conditions may intermittently allow communication over much greater distances.
What is the most powerful CB radio on the market?
Welcome to the most powerful CB radio available, the Ranger RCI 69FFB4. Boasting over 400 watts PeP, this Ranger CB radio puts everything else to shame in terms of sheer performance.
Do handheld CB radios need tuning?
Tuning your antenna is mandatory if you want acceptable CB performance. Not tuning your antenna will result in poor transmission and reception performance, and can also result in permanent damage to your radio. You’ll need an SWR meter (available for around $25) in order to tune your antenna.
How much does it cost to peak and tune a CB?
Out of the box, a CB generally produces 4 watts of output (1 or 2 mIles of range). Peaked and tuned, you’ll put out upwards of 35 watts (7-10 miles of range). 50 to 100 bucks for the package. P.S. don’t run your antenna like a Lance as some of the morons do.
Can high SWR damage a radio?
IMPORTANT NOTE: Radio damage will only occur when you’re TRANSMITTING from an antenna with high SWR readings.
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.
What is the range on a 40 channel CB radio?
CB radios have a range of about 3 miles (4.8 km) to 20 miles (32 km) depending on terrain, for line of sight communication; however, various radio propagation conditions may intermittently allow communication over much greater distances.
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.
How do I make my CB reach further?
The best way to extend the range of your CB, or any radio, is raise the antenna higher. Of course you will need a good quality antenna and Coax. For mobile operations the Wilson 5000 is probably the best.
Which CB antenna has longest range?
The type of antennas with the greatest range are the stainless steel 102″ whip antennas, which may not be practical for parking in garages, under trees, and so forth. The single center load antenna also has about the same transmit and receive range as the whip.
How do I increase CB power output?
There are several procedures for ensuring maximum output.
- TUNE THE RADIO. A CB radio is only as good as the coax and antenna connected to it.
- USE CB-SPECIFIC ANTENNAS.
- ESTABLISH A GROUND PLANE.
- CHECK THE VSWR.
- ELIMINATE RESISTANCE.
How do I get more power out of my CB radio?
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.
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.
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.
Does coax length affect SWR?
Coaxial Cable Length Does Not Change Antenna SWR.
