Tuning a cb antenna

By increasing or decreasing the antenna length,. Set the switch on the SWR meter to “FWD. Turn the radio to channel 1. Channel SWR is greater than Channel SWR. Use the appropriate tuning feature, discussed above,. OFF CENTER TUNING YOUR CB ANTENNA.

You can see that the SWR on the channel extremes is between 2. In this video Sean will show you how to properly Tune a CB antennae to get the best performance.

Using an SWR meter or a built in SWR meter you can calibrate your CB by shortening or lengthening. The tuning of the antenna must always be rechecked if anything in the enclosure has change even objects several centimeters away can have an impact. Sometimes, the antenna will need to be adjusted to get the optimal signal. Most fibreglass antennae have detachable segments at the top to allow for extensions, so antennae can be lengthened that way. Tuning a CB radio means fixing the antenna.

Antennae can also be shorted by sawing the antenna down as needed.

Setting the SWR of Your Antenna. Since the antenna was not tuned in the enclosure the impedance is not matched to the Ohm PCB trace line over the frequency of interest. Trending price is based on prices over last days. Attach the antenna to the antenna socket on the SWR meter using a coaxial cable.

Tune to the lowest band available. Observe and record the SWR reading. FREE Shipping on eligible orders. The commercial equipment available for CB radio has been vastly improved since the late 50s, but even with the latest technology, a CB radio transmitter is only as good as its antenna. Tune your CB Radio to channel 1(one) and set the SWR meter switch in the Forward “FWD” position.

Hold the CB in transmit mode by pressing the PTT button on the mic. Ajust the SWR meter needle using the Set or Ajust knob on the meter until the needle is in alignment with the corresponding mark on the meter. By applying this guide you able to talk miles away and.

A carefully tuned antenna will always outperform a poorly tuned one. Find All The Antennas Products You Need at Zoro. Orders Over $Ship Free on All Antennas at Zoro. SWR (standing wave ratio), is a measurement of how efficiently your antenna system will radiate the power available from your radio. When tuning CB antennas , I. Consider subscribing here!

FireStikII FS Series 2-Ft. CB antenna tuning means that you’re trying to get the lowest SWR reading possible. All CB antennas are tunable. Accordingly, lots of people think the other antennas are not tunable and so they make no attempt to have the antenna tuned. Transmitting antennas are not plug-n-play devices.

The antenna is the most important component of your CB system. This is a critical mistake. In addition to over years of HF-UHF antenna experience, I used to tune large antenna farms for the Air Force and we tuned each antenna only at the mid-point of the frequencies in use.

No need to tune at each side which only takes longer without benefit. Hope you can help me with a question on tuning a CB antenna. Is it possible for a CB antenna to be bad?

Aside from the ease of tuning , the patented design broadens the antennas bandwidth to keep SWR lower over more channels. The upper coil extension also increases the power handling capability of the antenna. Like all CB antennas , the KW antennas require fine- tuning (SWR) in their final mounting location.

The loading coil on all KW antennas is easily accessable for precise SWR adjustments. All KW antennas exceed the requirements of any CB radio, new or old. The Name in Over-the-Road Communication. Wilson CB antennas offer silver-plated copper wire for superior power and the broadband antenna allows for easy tuning.

Wilson offers CB antennas, studs, CB antenna mounts, cables and other accessories to meet all your needs. The ½ wave NGP (No Ground Plane) antennas do not require a ground plane (meaning, metal surface) but it is always best to have enough metal surface area over 2’x 2’ area. The SWR, or standing wave ratio, measures the impedance mismatch between the antenna and radio. Grounding the ground plane cable made the CB band near perfect for Standing Wave.

Firestik fiberglass antennas have an adjustable tuning screw at the tip of the antenna so that you can shorten or lengthen it to adjust the overall length of your antenna. A CB radio is only as good as the coax and antenna connected to it. However, the unit itself should be tuned occasionally by a reliable technician.

The system can be balanced by lengthening or shortening the antenna. Some antennas have a set screw to loosen to adjust the length of the antenna. Mounting the Set – CB ’s vary in size and shape as do the vehicles they are installed in.

Where you install the CB itself is only important in regards to its ease of access and the orientation of the speaker so you can hear it. The two most common are cutting lengths of wire off of your antenna , or, preferably, changing the depth of a tuning screw threaded into the end of the antenna , a la Firestik style. Firestik No Ground CB Antennas. Antenna : There are a couple ways to tune an antenna. The LG-Mseries, No ground plane (NGP) CB antenna kits were specifically designed to solve the problems associated with the lack of ground plane (counterpoise).

What an antenna tuner or transmatch does do, however, is transform the impedance at the antenna feed output at the radio to a value that your transceiver can handle, (typically Ohms).
