For me 5/8 are just easier to build and tune. Still it needs a ground plane and that does add mechanical complication of a different sort. Not much on two meters, use 3/4 inch wooden dowl or acrylic rod for supporting 3/4 inch tublar radiator. This also becomes the coil form for thre matching coil. Groudplane can be anythinh from stiff wire held on by a radiator clamp to a metal roof. Even with the radials going nearly straight down from the antenna it seems to work pretty well. Ive cobbled these to gether in an hour or so and have spent all evening making one look pretty. They both worked well and gave long service. Constuction goes a lot faster once you get some experience on where to tap the coil and know how many turns, One day I am going to write this down when I make one.However I find that figuring the right lengths for the 5/8 is not nearly as fussy as doing a J from scratch I dont mind J antennas a a horizontal dipole on HF where the stub length is convinent to handle. This can be a problem when you get on down in freq. I can use one on 20 meters at this freq the stub works well as my transmission line. For me J's work from 6m trhough 20 meters. Wouldnt dream of actually buying one though. I've built both and for differing reasons each works well when well made. I find making a 5/8ths harder to achive for say 2m or 6m out of copper pipe than a J. Allison KB!GMX |
