Re: J-pole portable antenna

Wire Jpoles
That ARRL article came out just as I got my license and I had a new dual band HT. I built the antenna and it worked. Later when I borrowed an SWR meter I found that the antenna was way off, about 4:1 SWR. I now make wire jpoles with a piece of 450 ohm ladder line about 19" long and a half wave single wire attached to one side of the ladder line. It does work well on both bands as checked by an antenna analyzer. I can post dimensions if anyone is interested.
