How long should my CB coax be?
18 feetSelect the correct coax length.
Many antenna manufacturers somewhat pre-tune the antennas utilizing 18 feet of coax which is why we generally recommend 18 feet of coax even if you don’t think that you need that much..
Can I use 75 ohm coax for CB?
RG-59 and RG-6 are 75 Ohm coaxial cables designed for cable television applications, they tend to have wide frequency response and low line loss. … You can use these cables with a 50 Ohm amateur radio antenna system, but because of the impedance mismatch, your SWR will be a little higher.
Does length of coax affect signal?
When it comes to signal loss over longer cable lengths, the basic rule of thumb is that a 50-foot cable can experience noticeable signal loss, and a 100-foot cable can drop as much as one-third of the original signal.
Can I shorten a coaxial cable?
Luckily, shortening your TV cable, or coaxial cable, is a relatively simple process that you can do on your own at home. So before you call the cable repair person or put some random plant or piece of furniture in front of that coiled TV cable, grab a couple of tools and shorten it yourself.
Are rg6 and rg11 connectors the same?
Both the RG6 and RG11 cables are 75-ohm cables that make use of F-type connectors. RG11 has a greater and longer range longer than the R6. To be more specific, the RG6 tops out at 50 feet before the total signal loss. The RG11 does better with more than 50 feet to about 10 feet.
How far apart do CB antennas need to be?
5’When installing a dual CB setup, you need an absolute minimum of 5′ between the two antennas. Anything closer, and the antennas will be too close to perform properly. Ideally, you should be closer to 9′ as a minimum for peak performance.
Does coax cable length matter?
Coaxial Cable Length Coaxial cable comes in varying lengths. The shorter and thicker the cable is rated will determine the strength of the signal transmitted. It is important to choose the right cable length and thickness.
What is the maximum length for coaxial cable?
Coaxial cable can be cabled over longer distances than twisted-pair cable. For example, Ethernet can run approximately 100 meters (328 feet) using twisted-pair cabling. Using coaxial cable increases this distance to 500m (1640.4 feet).
Can you use TV coax for CB?
The cable TV coax its self won’t work as an antenna. It also won’t work well for a feed line to a CB antenna as it is 75ohm cable and CB’s are designed for 50ohm feed line and antenna. Of course you could connect it to the radio, you might hear something, probably not much. Just don’t try to transmit.
Is LMR 400 the same as rg8?
RG-8 and RG8X are two different things. RG-8 is a thicker diameter, while RG8X is a little thicker than RG-58 (a typical mobile radio antenna cable), but not as thick as RG-8. LMR400 is a cable that’s about the thickness of RG-8, but is constructed differently.
How do you tell if your CB antenna is grounded properly?
If your CB antenna mount has a good ground, the multimeter needle should move all the way to the right when the probes contact these two locations. If you get very little or no needle movement on the multimeter, test that your meter is working properly by touching the two probes together.
What is the best grade of coaxial cable?
Coaxial cable designed for domestic television should be 75 Ohm, with RG-6 coaxial being ideal for TV. The best coaxial cable for HDTV is RG-11. This type of cable offers a higher gauge than others, which provides more space for signals to transfer.
How do you calculate coax cable length?
To calculate the electrical length of the line you need to multiply the velocity factor of the line (available from the supplier of the line) by the free space length. For the length in feet, this is (983.6 / frequency in MHz) * velocity. For the length in meters, this is (299.8 / frequency in MHz) * velocity.
Can you connect rg6 to rg11?
You can mix coaxial cable types. It’s very common for RG11 to be used for long runs and RG6 to be used for shorter runs. Typically you would switch cable types at an intermediate closet where the RG11 cable will go into an amplifier and RG6 cable will come out.
