2 Meter Quad Antenna Design Professional At HCJBW9LZX, (SK), an professional at HCJB, (á shortwave missionary radio stations station in the Andean Mountains ).He developed it to resolve issues with large coronaI discharges in thé slim air flow with a ray antenna. 2 Meter Quad Antenna Design Plus Going ForThis 3 component 2 meter quad design has a main plus going for it. Most contractors of VHF quads make use of PVC or timber as the growth, and solid wood dowels, PVC, fibergIass, or some additional non-conductive material for the spreader (support) hands. Wire is used for the element loops. Design above for highest gain at 146mhz ELEMENT LENGTHS FOR 14 Cable AT 146MHZ: This style only offers a good go with to 50 ohm coax using 14 wire and making use of the spacings and measures below.do not change unless you would like to experiment If you want to experiment with the design program, see information below. If that should happen to be too longer, you can always reduce off to fit when completed. It is usually finest to layout the individual loops for thé quad in án exact square pattern so they wont move. Just get the component size from over, separate by 4 for each part of the pillow. Then measure from one corner to the additional and include an inch or two. Dont cut yourself short Do not modify the complete length of the Ioops unless you have some really strange swr blood pressure measurements when carried out. Do not modify the element spacing on the growth Relating to the computations, you should have got an incredibly good match to 50 ohm coax by direct feeding. You must match the supports (spreader pubs and increase to the duration of the loopsnot the other method around. The dimension wire, lengths and spacing of the components are pretty critical for the close to 50 ohm impedance of the feed point. Your tested impedance may be slightly different credited to your design strategies, etc, but you should end up being close relating to the plan used. Notice below for the program info and a resource to download it. They must be safe and in as near a pillow design as probable on the spreader pubs. It can make no distinction which side the give food to point is on for top to bottom polarization. This makes for problems with assisting the feedline and additional methods must be used to avoid stress on the coax link to the loop. One instance above on the powered element will be to drill down 4 small holes big plenty of for the cycle wire to move thru and twisted back on itself providing some strain relief. After that the coax middle and face shield is extend out just plenty of to distort onto the loop finishes, soldered and after that the coax ends and the solder connections sealed from the climate.
