Which Swr Meter Works For Both Cb And Gmrs
One of the best swr meters you can get is this workman swr meter for cb radio antennas with a 3’ jumper cable. Our primary attraction on this meter is being able to work on cb radios with a frequency range of about 27mhz. After installing a gmrs radio, or any radio for that matter, it is a good idea to check the swr (standing wave ratio). Allow you to transmit a. Use the same measuring tool to measure the swr of the antenna at various frequencies.
Calculate the amount of trimming required: Determine the difference in frequency between the resonant frequency and the frequency at which the swr is highest. Easiest way to set gmrs radio swr. To set the swr on your gmrs radio, you’ll need the following tools: A cb swr meter won’t work on your gmrs. Each antenna is individually tested and tuned for optimum performance on their respective bands. The two meter antenna is tuned to 146mhz (1. 2:1 swr or less at 146mhz), and the swr is 1. 4:1 or less throughout the entire 2 meter band. This antenna also works great as a dual band antenna. A swr meter that covers gmrs frequencies will probably go sufficiently low to cover cb. In other parts of the world cb is uhf and immediately adjacent to gmrs band. So any swr meter for one will most likely work for both. The opposite doesn't hold true. You cah measure a low swr and still have an impedance mismatch. I’d also point out the cb swr meters are built for a single, very narrow frequency range and 5 watts of rf power. Swr meters that work on gmrs usually cover a much wider band.

My diamond sx400 covers 140 to 525 mhz and up to 200 watts. Do you have a cb, ham, or gmrs radio? Pick a meter that will work with the type of radio that you have. Frequency range and impedance ratings are some of the most important specs to determine a good fit for your radio. Otherwise, it will be useless, and you cannot. A good swr meter for cb & ham radios can test a wide range of frequencies at multiple power settings. Precise, lightweight, and capable of handling large loads without shorting out. He was adding you might be able to use your cb swr meter for some hf ham radio equipment, and that the principal of how they all work is the same. My answer stands though. You cannot use your current cb swr meter for gmrs. For gmrs you need an sur meter that operates at uhf frequencies. However, there are meters that operate over a broad range of frequencies. These tend to be more expensive and often require different “slugs” for each frequency range. If you want to maximise your radio antenna's performance, you'll need to tune it using an appropriate swr meter. An swr meter helps ensure clear transmission and can even detect significant issues with your radio. Cb is a pain to set up since it needs to be properly grounded and tuned, if you do it yourself you'll want to have a multimeter and swr meter for the install.

They're also handy for listening in on truckers when you run into an accident or backup on the highway and want to know which lane to be in. An swr meter (or directional watt meter) will allow you to actually test things under the full rf power. The nanovna only uses a very low power signal that may not show some issues with antennas. That's ok for most hobby stuff, though. If it'll work on 10m, chances are it'll be fine for 11. [deleted] • 5 mo. Can someone recommend a swr/power meter that will work on gmrs frequencies? Too high of an swr reduces performance(range) and can potentially damage your radio, though the latter is more of an issue the lower you go in frequencies or higher you go in power. An swr meter will only show you the swr of the antenna for the frequency you're transmitting on and it can be completely wrong if you're looking at a system with lossy cable. An antenna analyzer connected directly to the antenna can.
