A typical ferrite core transformer as above with a 7:1 turns ratio (49:1 impedance ratio) or more will be "helpful". 9 meters wire at its end. There are many articles on compact 160 m antennas, but this is not one of. A really quick antenna for 2 metres and 70 centimetres, made from just 2 metal coat hangers and a small length of strip connector just add the fun. RADIATION PATTERNS OF ANTENNA 2 A conductivity of 0. To find the half wave, dividing 3. Grounding: From the ground terminal on your radio (next to the antenna terminal) run a wire to either a copper cold-water pipe (PVC pipe won’t work) or a copper ground rod driven into the ground. DXCANADA brought you another long wire multi band shortwave HF antenna 1 x Balun; 1 x 20m Main Element; 2 x 1. Custom designed and built 2. Length in feet = 234 / Frequency in MHz. It can also be used as an indoor attic emergency backup antenna after a suitable location and mounting is found. Dipole Antenna Calculator The measurements below are for building a simple Dipole Antenna. More coax is good in this case because its more antenna to radiate. 2 Meter Whip Dipole Antenna By Jose B Rivera - N2LRB February 8, 2015 - My quest to make a reliable 2 Meter dipole antenna for use on 144.

Carr · More Antenna Classics - C. It is up in the 3 - 4 K ohm impedance range. Some Notes on the Slim Jim Antenna - M0UXB. Again you will have a good match for 50 ohms coaxial cable and now have the makings of a long wire antenna with gain. 37 inches long, the equivalent of 3. The feed impedance of the end fed long wire antenna is perhaps the main consideration particularly as in this. Example — 2 meters: If you are operating on 144. Trim the wire ends to extend about 1. On the right is the 40 meter SWR plot. Random Wire Antenna Lengths. this line is connected to the long wire, which has length exactly 1/2 wavelength. This is so because here a long straight wire is considered whose length is a multiple of λ/2. 10 Best 2 Meter Mobile Antennas. This is only partly the case with these Hari long-wire antennas, in order to keep the length in a manageable size. Slip about a one inch piece of the heat shrink past this area, you'll be bringing it back later. Turns are counted by the number of times the wire passes through the toroid center. 28 feet long, so 40 meters is 40 X 3. 40m/80m Portable antenna.
