How do I adjust my CB antenna?
CB Antenna Tuning InstructionsThe first thing you need to do is find a suitable location to park your vehicle.
The next step is to hook up the SWR meter.
Now you are ready to measure the SWR on a few different channels.
Set the switch on the SWR meter to “FWD.”Turn the radio to channel 1.Key the microphone (depress the button and hold it).More items….
How far can you communicate with a 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.
Does SWR affect reception?
Simplified answer: There is no relationship between SWR and receive performance. … SWR is a measure of the impedance mismatch between your antenna and transceiver. Whether transmitting or receiving, a higher SWR correlates with a less efficient coupling of energy between the transceiver and antenna.
What is the most powerful CB radio on the market?
What Are The Most Powerful CB Radio Are:Best Overall – Cobra 29 LX 40.Best Heavy Duty – Uniden BEARCAT 980 40 Channel SSB.Best Portable – Midland 75-822 40 Channel.Most Rugged – President Electronics MC KINLEY.Premium Choice – Galaxy-DX-959 40 Channel.
Does antenna gain affect reception?
When transmitting, a high-gain antenna allows more of the transmitted power to be sent in the direction of the receiver, increasing the received signal strength. When receiving, a high gain antenna captures more of the signal, again increasing signal strength.
What is the best CB radio for long range?
Cobra 148 GTLBest Long Range CB – The Cobra 148 GTL Our favorite SSB equipped radio is the Cobra 148 GTL. If you read the description of the Cobra 29 series above, much of why we like the 148 GTL will sound familiar. It’s been around forever, is super reliable and gets the job done without complaint.
What is an acceptable SWR reading?
What is a good SWR reading ? The best reading possible is 1.01:1 (46dB return loss), but usually a reading below 1.5:1 is acceptable. Outside the perfect world a 1.2:1 (20.8dB return loss) is spot on in most cases. To ensure an accurate reading, it is best to connect the meter at the base of the antenna.
What does 42 mean in trucker talk?
Yes, or OKQ: What does “42” mean? A: If you hear a truck driver say “42” on their CB radio, it’s just another way to say “Yes, or OK.” There are hundreds of other popular CB slang phrases – to learn more, check out the links below or browse the rest of our online CB slang dictionary.
Are CB radios making a comeback?
Many thought citizens band radios would disappear after the 1970s, along with pet rocks and disco. But not only are they still around, they are making a comeback. CB radio sales have increased steadily during the last three years, a trend not seen since the 1970s.
Is higher or lower antenna gain better?
The higher the dBi number of the antenna, the higher the gain, but less of a broad field pattern, meaning that the signal strength will go further but in a narrower direction, as illustrated in the diagram below.
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. … If you have an antenna that’s say, three feet or less, and the SWR tunes great (less than 1.5) across all the channels than maybe your antennas feedline coax or the antenna coil is “lossy”.
