Hi Richard,
Thanks for the link to the archives, I will check it out. I imagine there a few hams who want to make their own ladder line these days. Other than finding some vintage ceramic spacers (rare) what are they using? Apparently paraffin soaked dowels are not without some shortcomings. I think there is at least one ham who has a cottage industry selling his homemade version ladder-line which, from what I can gather, utilizes the black poly piping that I mentioned earlier. I think I came across at least one ham who has used the grey UV/PVC pipe which he slices (saws) lengthwise and then drills holes and/or notches etc. This seems a bit labor intensive if one wants to make any quantity, but maybe not as much as I think. If the UV/PVC pipe is a good solution, I might be able to track down a source of 3/8" UV/PVC pipe which I would not slice up, but just cut into 6" lengths and then devise a fastening system on either end for the wire.

Hi Bill, Each formulation seems to be distinct, but offhand I don't recall which is which. To broaden your experience with this forum, visit: http://groups.google.com/groups?oi=d...mateur.antenna and checkout their advanced search page. Use "PVC" and "Loss" as keywords in the search. The topic is not so novel as to be sparsely represented in the archive. 73's Richard Clark, KB7QHC |
