Brad, AA1IP, has come to the rescue and is offering Belden 1671A at prices SIGNIFICANTLY below cocaine levels. Thanks Brad!
Hello--
In response to Bill's plea on SolderSmoke #142 for an inexpensive source of Belden 1671A semi-rigid coaxial cable, I can offer it for sale at $.30 per foot in lengths up to 10 feet to 20 feet; handling longer lengths is problematical, as I don't have a good wire-respooling method at present. Postage and packaging for up to 10 feet of 1671A cable is extra and costs $3.25 for shipping via first-class mail to U.S. addresses (I honor PayPal and certain other payment methods). Note that coaxial connectors for 1671A are available (but not from me, alas). Also, the outer jacket of 1671A is best cut with a fine-toothed coping saw or a miniature tubing cutter such as... http://www.amazon.com/Pit-Bull-Mini-Tubing-Cutter/dp/B0027BBHW0
Questions welcomed as always. 73-- Brad AA1IP
P.S.: the "Murphy's Whiskers" Bill refers to are small pieces of copper braid wire that break off from RG-174/U (or other) coax braid and cause intermittent short-circuits in whatever they fall into.

ReplyDeleteI should have mentioned this before but you were too excited about semi-rigid coax:
ReplyDeleteYou can get the same results with Teflon insulated conventional coaxial cable. Simply tin the braid completely before you cut it. Since the Teflon center insulation doesn't melt, the braid will slip off after cutting. The same methods of cutting can be used as those used for cutting semi-rigid cable; either tubing cutter or "Razor Saw".
FWIW, I don't particularly care for the tubing cutter method; it deforms the shield and introduces an impedance "bump" although that may not be as problematic on HF as it would be on UHF and above.
