Hello The Net:For my vertical antenna guyed in three direction at 4 levels, I am planning to use 3/16", polyester, braided, of double braid construction. Original guys were of the military surplus type, part of a GRA-4 antenna system and part number MX-383A/GRA-4, that uses, 1 each, insulator in line. For replacement guys, can I remove the insulator and only use the braided line ? With wet guys (after rainstorm) I measure the (~ DC) resistance from the vertical to ground as greater than 6 megohms, my meters capability. What are your thoughts ?I can add the insulators, but I would also need to add crimped connectors or other rope clamps, that would reduce the ultimate reliability of the guy. The vertical is constructed of MS-44 aluminum masting sections stacked up to 50', (maybe 55 or 60'+ later). Final plan is to add a capacitive top hat with 8 each, 20' radials and a center loading coil for use on 2200M and 630M. Probably a additional switchable base loading coil for 2200M tuning (TBD).
