How do I ground my CB antenna?
Ground Your Antenna Mount
To ensure a good ground, check that your mount has a direct metal-on-metal connection to your vehicle’s frame. Depending on the location of your mount, paint or powder coating can interfere with this connection. If this occurs, you’ll need to scrape a bit of the paint or powder coating off.
What does the ant light mean on a CB radio?
A common reason for the ant light to light up is that the antenna is not grounded properly. Check out this page from Firestik for more information on swr and cb’s. If your ant light is on when you transmit, stop using the radio and fix the swr. You will ruin the radio. Good luck and enjoy your cb radio!
How do I lower my SWR?
If your antenna is mounted down low on the vehicle, like on the bumper or behind a pickup truck’s cab, the signal can bounce back to the antenna, causing a high SWR. To alleviate this, keep at least the top 12 inches of the antenna above the roof line, and position the antenna as high as possible on the vehicle.
What does an SWR meter do?
The standing wave ratio meter, SWR meter, ISWR meter (current “I” SWR), or VSWR meter (voltage SWR) measures the standing wave ratio (SWR) in a transmission line. The meter indirectly measures the degree of mismatch between a transmission line and its load (usually an antenna).

How do I know if my CB antenna is grounded?
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.
Do magnetic CB antennas need grounding?
Usually this surface is part of the vehicle (roof or trunk) which is at the vehicles’ electrical ground and thus can make more of the vehicle part of the grounplane. The antenna itself does not need an electrical ground.
What does TX mean on a CB radio?
so the Tx means output transceiver, and Rx input transceiver.
What is Tx on a CB radio?
It doesn’t have an SWR meter, only one that is supposed to very roughly indicate the TX (transmitting) and S/RF (receiving) signal strength.
What is Delta tune on a CB radio?
The delta tune is the CB name for a very similar function on amateur radios called RIT, or receive incremental tuner. The Delta Tune controls the frequency your radio’s receiver is operating on.
Is 1.7 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.
How do I test a SWR antenna?
To run a test, simply connect your radio’s coaxial and antenna cables to the indicated ports on the meter. When you set the meter for calibration and activate the radio transmitter, you’ll see a number indicating the strength of the signal being broadcasted. SWR is typically only tested on mobile or base installations.

Does SWR affect reception?
Simplified answer: There is no relationship between SWR and receive performance. There is one condition for this simplification to be true: the received RF noise floor must be above your receiver’s noise floor.
Can high SWR damage a radio?
High SWR can reflect enough power back into the radio to create enough heat to cook the final RF transistor. It isn’t usually an immediate failure, it takes some time for that heat to build up and do damage.
