Question: What Is The Best Height For A CB Antenna?

How far apart do CB antennas need to be?

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..

How far will a 4 watt CB transmit?

Car, Boat, & Other Radios (Mobile & Fixed-Mount)Average Range Guidelines *WattageFlat Open Terrain (miles)Urban Areas (miles)4 watts (UHF)4 – 61½ – 35 watts (VHF)4½ – 61½ – 212 watt CB SSB (HF)8 – 153 – 55 more rows

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. A bad ground will result in an un-tunable antenna and sky-high SWR levels.

How do I increase the range on my CB radio?

How to Increase the Receiving Range on a CB RadioInstall an antenna specifically manufactured for use with CB radios. … Place your antenna as high as possible, in a place where radio signals can hit it from 360 degrees. … Adjust the squelch on your radio so that it blocks out static, but is not maxed out.More items…

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 coax length affect SWR?

“the length of the feedline will not change the swr it will change the apparent reading depending on what wave length you read the swr at. . just as adding a signifigant length of coax, the resultant loss will look like a lower swr.”

Is a longer CB antenna better?

Choosing the Optimal CB Antenna Length Yes, taller/longer is better for range of distance when it comes to an antenna and the optimal antenna length is 1/4 wavelength. That translates to 102 inches (8.5 feet), too tall to be practical for most mobile applications.

Does CB coax length matter?

CB coax cable is necessary to connect your antenna to your radio. The coaxial cable running from your radio to the antenna is VERY important. Everything you transmit and receive must travel along it’s length. All too often, the coax is ignored and performance suffers because of the lack of attention it receives.

Can you mount a CB antenna horizontal?

If you mount it horizontal it will still work but will lose about 70 percent of the vertical range. For trail riding it will be fine. The antenna cannot be perpendicular to a metal roof or roll cage this will cause reflected power resulting in a high SWR.

What is the best performing CB base antenna?

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.

How far will 25 watts transmit?

For example, a 25-watt marine radio will roughly have a maximum range of 60 nautical miles (111 km) between antennas mounted on tall ships, but that same radio will only have a range of 5 nautical miles (9 km) between antennas mounted on small boats at sea level.

Why is my SWR reading so high?

The most common cause of a high SWR is an antenna shorted to ground. There are two places a short can occur in a CB antenna system, in the coax and in the antenna stud.

Where is the best place to mount a CB antenna?

The best place for your standard antenna is the center of your roof, where you will have the greatest ground plane coverage. When you install a CB antenna on the fender, bumper, or anywhere else around the edge of your vehicle, you will have a weaker signal going away from the vehicle.
