Quick Answer: Can SWR Be Too Low?

Are rg59 and rg6 connectors the same?

The main difference between RG6 and RG59 is that the RG6 cables have a thicker copper wire allowing better transmission of the signal.

RG6 is primarily being used today for satellite and digital cable TV, where higher frequencies are required that RG59 cable cannot support..

What does an SWR reading of 4 1 indicate?

What does an SWR reading of 4:1 indicate? Loss of -4 dB. Good impedance match. Gain of +4 dB. Impedance mismatch.

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.

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.”

Does SWR change with power?

SWR really doesn’t increase with power. It’s always the same.

What is the range of 5dBi antenna?

about 500 metersThis antenna would typically replace standard 2dBi antennas, which are normally shipped with this class of wireless device, in order to increase the range and/or expand the coverage area. With this 5dBi antenna, theoretically a distance of about 500 meters can be covered.

What is acceptable SWR?

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.

Is 1.5 SWR good?

SWR RANGE EXPLANATIONS. SWR 1.0-1.5: The ideal range! If your SWR is under 1.5, you’re in great shape. If you’re at 1.5 and really, really want to drop down to closer to 1 it’s likely possible to do with addition tuning, different equipment or a different mounting location.

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.

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.

Does a 1/2 wave antenna need a ground plane?

Answer: No. The 1/2 wave antenna (also called a dipole antenna) is built of two 1/4 wave elements that interact with one another to launch the electro-magnetic wave. It does not require a ground plane to work efficiently.

How do I know if my CB antenna is bad?

Testing for a Defective CB AntennaUsing your multimeter, touch one of the probes to the metallic end of the antenna. For fiberglass antennas, this will usually be the tunable tip on the antenna’s end. … Touch the other probe to the metallic threads at the end of the antenna. … As you maintain contact with both probes, measure the circuit’s resistance.

What SWR is too high?

For instance a SWR too high (over 3:1) all over the band can be an indication of a bad part or junction, poor ground or poor location. 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.
