How long can a CB antenna wire be?

However, wire lengths range from 20 feet to 32 feet (0.6 to 0.9 of a full wave length). If wire length was relevant, each antenna would need 22.5 feet of wire.

How long should a CB antenna cable be?

We recommend 18 feet of coax even if you don’t need that much. 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.

Can antenna cable be too long?

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.

Does coax length affect SWR?

Coaxial Cable Length Does Not Change Antenna SWR.

How long is antenna wire?

When you say “Antenna Cable”, do you mean Coaxial Cable, like this? If that’s the case, you can theoretically run it about 500 meters (1,640 feet) without needing amplification.

Will a CB work without antenna?

Scientific fact: CB radios work better without an antenna.

Does my CB antenna need to be grounded?

Ground Your Antenna Mount



If you’re using a standard CB antenna (i.e., anything except a no ground plane, or NGP, kit), you’ll need to make sure your antenna mount is solidly grounded to the vehicle’s chassis. … To ensure a good ground, check that your mount has a direct metal-on-metal connection to your vehicle’s frame.

What’s the difference between coaxial cable and satellite cable?

The satellite cable is higher grade (ie, thicker), but the impedance of both is 75 ohms, so you can use satellite cable for Freeview, but not the other way round. …

Is 1.5 SWR good?

SWR 1.0-1.5: The ideal range! If your SWR is under 1.5, you’re in great shape. … Occasionally, due to installations or vehicle variables, it’s impossible to get SWR lower than than this. You should try to get it lower, but performance should still be acceptable in this range.

What is the best height for a CB antenna?

Generally, the higher the antenna is above ground, the better it will perform. Good practice is to install your vertical antenna about 5 to 10 feet above the roof line and away from power lines and obstructions. Remember that the FCC limits your antenna height to 60 feet.

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.
