Can I use a CB SWR meter for ham radio?
Many hams have re-purposed CB SWR meters but there are so many variations that some caution and testing is warranted. Many CB meters were not designed to handle the higher power levels of amateur transceivers. A 100 watt transmitter could cause component failures within the meter.
How do I check the SWR on my 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.
How do I tune my antenna?
Attach the radio to the transmitter socket on the SWR meter using a coaxial cable. Attach the antenna to the antenna socket on the SWR meter using a coaxial cable. Set the radio to minimum power and to FM or CW mode. Tune to the lowest band available.
Do I need an SWR meter?
To tune your antenna, you will need to use a SWR meter. This device is attached between your antenna and radio. This device measures the amount of signal being reflected into your transmitter to help you measure the quality of your outgoing broad cast as well as any potential threat to your radio.
How do I test a SWR meter?
With the meter correctly hooked up to radio and antenna, set the switch to the “REF” position. Turn the SWR calibration knob fully counter-clockwise. Key the microphone and, while continuing to depress the talk button, adjust the calibration knob so that the needle touches the “SET” mark on the meter.
Can I use a CB antenna for 2 meter?
It’s a 5/8 wave all stainless steel base loaded whip antenna with a threaded 3/8X24 base which is the same as most CB antenna’s. Its 49″ long and can handle 100 wattts and designed for 2 meter.
How do I check my SWR without a meter?
How To Tune A CB Antenna Without An SWR Meter?
- Step 1: Find the open location.
- Step 2: Check the antenna before tuning.
- Step 3: Prepare one more CB radio.
- Step 4: Set Up An Association Between The CB Radios.
- Step 5: Use A Microphone.
How does an SWR meter work?
A directional SWR meter measures the magnitude of the forward and reflected waves by sensing each one individually, with directional couplers. A calculation then produces the SWR.
How do I adjust the SWR on my antenna?
Turn the radio to channel 1. Key the microphone (depress the button and hold it). Turn the knob on the SWR meter labeled “SET” or “ADJUST” until the needle reaches the setting position at the end of its range. While still keying the microphone, flip the switch on the SWR meter to the “REF” or “SWR” position.
How do you hook up a SWR meter to an antenna?
Your SWR meter needs to be connected into the coax between your radio and antenna. For this you will need your meter and a short jumper of coax with the correct connectors on it (usually PL-259s). Connect one end of the jumper to the back of your radio. Now connect the other end to the “Transmitter” socket on the SWR meter.
Do you need a VHF SWR meter for ham radio?
If all you want to to is check SWR on your 2M antenna, you don’t necessarily have to buy a dedicated VHF/UHF SWR meter. What I keep in my toolbag for that is a cheapie $5 hamfest special CB SWR meter.
Where is the transmitter port on a SWR meter?
Connect your radio’s coaxial cable to the transmitter port on your meter. This port will be located either on the side or back of a standard SWR meter. It should be marked “transmitter” or “XMIT.”
Is there a SWR meter for 2m radio?
They really don’t work well on 2M but there’s a trick you can do that will net a reasonably accurate SWR reading on 2M with one of these meters. What you do is connect up the meter as usual, key the rig with the switch in the forward power position, set the adjustment for full scale.
