I haven't been following this thread until now, but are you building these antennas for portability or are you using them in a base configuration? I've found 300-ohm twinlead to be the best as far as portability and ease of construction. I live in the Portland Oregon area and haven't seen any 450-ohm ladder line, anywhere, at least not for sale. I've never worked with it so I really can't make many comments on it, but it would seem to be harder to work with and the physical size wouldn't make it condusive to back packing! Personally, I have a copper J-Pole that I can break down and take with me every where I go. I also have the twinlead J-Poles that have served me well in most mobile situations! Just my thoughts!

LB Cebik did an in depth comparison of the two antennas and found the J-Pole to be slightly better in performance. Recently, our club had a J-Pole antenna building party and it was difficult to get them tuned up where we wanted them using TV twinlead. My best success with homebrew verticals has been when I used 450 ohm slotted line, but I have never tried building the SlimJim's. Maybe they are easier to match? 73, Rick, KV9U Alan Wilson wrote: > You can build 2m slimjim out of 450 ladderline for less than 5 > bucks...Look on http://www.hamunive rse.com, I've built several and > they are very easy to construct, easier and better than the > jpole...73, Alan
