Hello, I just obtained an Arrow Antena OSJ 146/440 J-Pole, installed it, then later read that a Balun is needed for J-Poles. But is one needed for this J-Pole? http://www.arrowantennas.com/j-pole.html It appears some J-Poles say there should be, and some don't mention it. - ARRL Antenna Handbook (on 2m copper JPole), says 3 loops of coax 8" in diameter - http://www.n7qvc.com/amateur_radio/copper.html, no mention - http://www.alpharubicon.com/elect/jpolejaden.htm, no mention I didn’t leave enough coax to create a Balun from a few loops of coax. Does this specific Arrow J-Pole need a balun? I’m getting 1.4 SWR right now without one. What would be better with the coke balum? Would it improve SWR, reception (less noise), or anything else? If I do need a balun, is there one that’s just an inline PL-259 adapter I could screw between the feed and the antenna? Or should I cut some more coax to make the loops (I’d use PL-259 on each side with a gender changer to connect the two cables, there’d be loss, but if it’s needed, then so be it). If loops are used, what would you recommend? I’ve heard three loops 8” in diameter, is that right? Thanks!
