This is a fairly inexpensive dual band antenna. The SWR checks reasonable on 2M, but on 440mHz, it is between 1.6:1 and 1.9:1, and the lowest SWR is at 450mHz. There is an internal adjustment with a setscrew at the bottom of the whip. Would this affect both bands? I would like to get a little lower SWR on 440 without compromising performance on 2M.
With it lower, as shown above, the SWR was around 2. For the elements, 38 inches (total, including the gap) should give you a low SWR across the band. If it doesn’t, try changing the antenna’s environment before altering the antenna. You can also adjust the SWR somewhat by changing the dangle-angle of the coax. To check transmitter power and antenna adaption, with two separate measurement lines, one 1.8 at 200 MHz, and the other 140 at 525MHz.

Turn the transmitter of and disconnect the antenna coaxial cable at the NEVER attempt to adjust the set to the antenna.The other thing is climates: One common ‘downside’ to using a giant coil antenna for those that mobile in cold climates, the giant coil antennas will ice up when below freezing, and in snow will fill up. That detunes the antenna, and will make for a high SWR until the antenna is cleared of ice and snow. How do I check the SWR and what is the SWR cal knob used for? Get answers to your CB radio controls here Here's a step by step process for setting or tuning the SWR on your CB antenna What about dual antennas?: The process is the same, just adjust both antennas at the same amount.What sets this antenna apart from the rest is its multi-purpose arrangement designed to provide Depending on how you install your antenna—particularly the height—will affect performance. It comes with dual TV outputs so you can connect more than one TV in the absence of a splitter.You can set it up within a few seconds on cars, vans, SUVs and any other vehicle which has a steel or metal body. Once you place it in the vertical position, the antenna becomes omnidirectional. Since each Nagoya UT-72 antenna is dual-band in nature, it can support both frequency ranges of 136-174 MHz and 400-520 MHz. Feb 07, 2013 · The standing wave ratio (SWR) meter is used to check the standing wave on the Wilson 2000 antenna before any adjustments are made to the antenna to lengthen or shorten the height to change the standing wave.

Here are a few things you can check if...If that distance cannot be achieved, that alone should not discourage you from using co-phased antennas as you will still receive most of the benefits of a dual antenna set-up. However, spacing less than five feet (1.5m) may require some special tuning skills in order to achieve satisfactory SWR readings. I first learned about SWR thanks to a video tutorial by Leigh Halliday: "React Data Fetching with Hooks using SWR". If you're not familiar with SWR, you can watch Leigh's video, read the official docs or find more on dev.to. In this post we're going to build our own version of SWR, if only to understand how it works. But first a disclaimer: Before keying the transmitter, turn the calibration con- trol fully counterclockwise and select the high power range to protect the meter. When SWC-I and/or SWC-2 is connected, place the coupler switch in the (SWC-1/SWC-2) position (lower side), and when SWC-3 is connected, place the switch in (SWC-3), upper side.
