Jun 08,  · A " whip may be cut down for a 1/4 wave 6 meter antenna, (or 5/8 2 meter) but will be a little stiffer than desired for mobile, depending on the individual whip. A 1/4 wave whip for 2 meters is more practical from a size and performance standpoint and will work about as well as the 5/8 wave. but the optimum length required for matching will be found to be somewhat longer. The inner diameter of this par- the 2-meter band. Shortening the stub to move the maximum VSWR point higher in frequency is easy. Should you over- Constructing a Simple 5/8 Wavelength Vertical Antenna for 2 Meters. The height of the 5/8 antenna. To reduce the ground effect, 5/8 wavelength antenna should be installed at least 1/2 wavelength above ground to wavelength above ground. For best result, adjust the length of the antenna to get the smallest SWR, or adjust loading coil for the best matching impedence.

5/8 wave 2 meter antenna length

The 5/8 wave antenna consists of a vertical radiator which is fed at the base of the antenna. This page allows you to calculate the length for a 5/8 wave antenna. Since the formula calculates the antenna to be about 2 foot shorter, be sure to. Making your own 2 metre ( MHz) 5/8th wave whip antenna The table below shows how the vertical radiator length varies with frequency (@ % .. I stumbled across your site when looking for designs for 5/8 antennas for 2M. 2 shows a UG/U connector be- the 2-meter band. Shortening the stub to but the optimum length required for attach a ground plane and check the. The Firestik 2-Meter antenna is an omni-directional antenna for the to MHz, 2 meter amateur band. This 5/8 wave (physical & electrical) antenna has a nominal impedance of ohms and The over all length is " (cm) . 5/8 antenna could have about dBi gain over a 1/2 wave length antenna ( mounted same Power meter or SWR meter is helpful for that fine tuning process. my question is what would be the total length i would need for it to be a 5/8 wave antenna. i am terrible at math thats why i am here asking the. Most of them tend to stick to vertical antennas with a 1/4 or 1/2 wave sizing. a length of meters to do experiments with vertical antennas. Jun 08,  · A " whip may be cut down for a 1/4 wave 6 meter antenna, (or 5/8 2 meter) but will be a little stiffer than desired for mobile, depending on the individual whip. A 1/4 wave whip for 2 meters is more practical from a size and performance standpoint and will work about as well as the 5/8 wave. It is inversely proportional to the frequency which means the wave with higher frequency will have shorter wavelength. This calculator will help you to calculate the different wavelength of antennas based on . Loop antenna lengths are based on using / FMhz = total loop length in feet. As with any antenna, lengths should be cut longer than formula results and then trim as needed for best swr. The chart covers all ham bands from meters through 2 meters only. For us DXers it has no advantage of building or buying a vertical antenna with a longer length then about 7 meters. which are divided many times so they tend to be weaker. Above we see the pattern produced by a 5/8 wave antenna with a length just under 7 meters. This page allows you to calculate the length for a 5/8 wave antenna. It uses the standard formula, /f (/f for metric) MHz to calculate the element lengths. If you've experimented with 5/8 wave antennas before and know of a better formula for your QTH, feel free to change the formula to suit. Experimented with your plan for a 5/8 wave 2M antenna today, it worked very well. I used a piece of galvanized wire from my garage, stiff material used to bind things up. I started with a length 60 inches long, made a very crude coil on one end, 3 1/2 turns about 1" diameter, then inserted the end of the coil into a mag mount formerly used as. MFJ 5/8 wave ground plane 2m base antenna product reviews by real people like you. Only at rentyauto.com - rentyauto.com is a Web site dedicated to ham radio (amateur radio). The height of the 5/8 antenna. To reduce the ground effect, 5/8 wavelength antenna should be installed at least 1/2 wavelength above ground to wavelength above ground. For best result, adjust the length of the antenna to get the smallest SWR, or adjust loading coil for the best matching impedence. but the optimum length required for matching will be found to be somewhat longer.
