This would give me between 2.00, to 1.7 to 1 SWR at the bottom of each band. The upper end was left to fall wherever it ended up, in most cases the top end fell past the high end of each ham band.Once 20m is tuned, repeat with adjusting the coils for 30m and 40m. A fairly cumbersome process, but for three frequency ranges on one antenna, it was a half-hour project at most. In the end, the antenna is less than 2:1 SWR across all of the 20m band, all of the 30m band, and all but the top 50 Khz of the 40m band. Vertical element - 234 / MHz or 234/14.1 = 16' 7" 20 Meters was chosen for a test case because the size is easy to work with and it is a good band for testing and making contacts on most any day at any time. Also, 20 Meters is about the lowest frequency antenna with a low VSWR bandwidth that covers the full band.the frequency of 50.150 MHz for the 6-meter band and 28.300 MHz for the 10-meter band as the "target" frequency for lowest SWR or reflected power (depending on whether or not you are using an SWR bridge or a wattmeter). Put the antenna in the horizontal plane in an open area, preferably outside.You can also use these traps to design HF vertical multiband antennas using either wire or aluminum tubing.

This would give me between 2.00, to 1.7 to 1 SWR at the bottom of each band. The upper end was left to fall wherever it ended up, in most cases the top end fell past the high end of each ham band.The stand is plenty stout to handle the 23.5 foot aluminum vertical element. I had the aluminum and the wood and only had to spend a few dollars for some hardware and. UPDATE 10/16/07 Scroll down below the 30 meter antenna pictures and see my 17 meter "sorta vertical" that I mounted on the side of this mount. Using the general formula for a 5/8 wavelength vertical antenna, 585/f (MHz)=L (ft)/178.308/f (MHz)=L (meters) and a chosen frequency of 28.4 MHz, I cut seven pieces of #14 AWG wire to a length of 20.59 feet/6.28 meters. Six wires would be used for the elevated radial system. One wire would be used for the main vertical element.Also, this antenna has very hight SWR, especially on the low bands. It also has very high voltages and currents on your feed line. Let's look at the SWR on a typical 43 foot vertical antenna: 160 Meters: >100:1. 80 Meters: >100:1. 40 Meters: 7:1. 30 Meters: 23:1. 20 Meters: 27:1.Quater-wavelength in meters: 71.5 / frequency in MHz.
